Version 2.2.5

* Stephen Moshier implemented powl and cbrtl for the 128-bit
  long double format.

* Masahide Washizawa contributed iconv modules for IBM1160 and IBM1161
  charsets.

* Andreas Jaeger contributed a port to x86_64/Linux.

* libc functions using I/O streams now can handle wide-oriented streams
  as well.

* optimizations in the dynamic linker.  binaries created by recent binutils
  versions start up quicker due to reduced time spend on relocations.

Version 2.2.4

* Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh,
  asinh, atanh, j0 for the 128-bit long double format.

* Bruno Haible updated all the code handling Unicode in some form to
  support Unicode 3.1.

* Speed of regex for single-byte locales is back to previous levels.
  Patch by Isamu Hasegawa.

* Alpha, SPARC, and IA-64 now also using floating stacks.

* Startup time of internationalized applications greatly improved through
  iconv cache.  Use iconvconfig to generate the cache file.
  Contributed by Ulrich Drepper.

* The IA-64 specific part of ld.so was rewritten to eliminate some pretty
  severe performance problems.  Patch by David Mosberger.

* The Hurd port got a lot more functionality like AIO, various stdio
  extensions, etc.  Mainly done by Roland McGrath.

* mtrace can now lookup symbols in shared libraries.

Version 2.2.3

* Intel's IA-64 math library is largely integrated.  It provides fast and
  accurate implementatations for most basic and standard math functions
  in float, double, and long double format.

* Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
  and asin for the 96-bit long double format and asin, log, tan for the
  128-bit long double format.

* The beginning of a last-bit accurate math library by IBM Haifa were added.
  The basic double functions exist today.  Contributed by Abraham Ziv
  <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
  <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.

* An asynchronous name lookup library was added.  The interface is designed
  after POSIX AIO.  The proposal was circulated beforehand to get comments.
  No negative ones came in.  Implemented by Ulrich Drepper.

* Port to S390/64bit contributed by Martin Schwidefsky
  <schwidefsky@de.ibm.com>.

* David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
  of functions for Linux/IA-64.

* The RPC code is now thread safe.  Threads can now use the same service
  of different services at the same time.  Patch by Eric Norum
  <eric.norum@usask.ca> with some help by Ulrich Drepper.

* Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
  family of functions for Linux/S390.

* Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
  of functions for Linux/x86.

* Port to Linux/CRIS contributed by Axis Communications.

Version 2.2.2

* Lots of headers were cleaned up.  Using the tool in the conform/ subdir
  we can now check for namespace violations and missing declarations.  The
  result is that almost all headers are now Unix-compliant (as defined in
  the upcoming XPG6).  The negative side is that some programs might need
  corrections, too, if they depend on the incorrect form of the headers in
  previous versions which defined too many symbols and included too many
  other headers.

* regex now handles multibyte character sets correctly.
  Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.

* iconv (the program) does now conform to the upcoming XPG6 and handles
  charmaps.  Instead of the charset names the path of charmaps can be
  provided and the conversion happens based on this data.
  Contributed by Ulrich Drepper.

* The locale program now provides detailed information about the installed
  locales.  While

    locale -a

  only lists the names of the supported locales

    locale -a --verbose

  provides details such as country, language, and codeset name.
  Contributed by Ulrich Drepper.

Version 2.2.1

* The gencat program now parses the input file according to the charset
  selected by the LC_CTYPE category.  This is important for stateful
  character sets.  To make generating catalogs easier there is a way
  to overwrite the charset selected by the locale: before the first
  message or $ quote line the catalog can contain a line like

    $ codeset=ISO-8859-2

  to select the charset (ISO-8859-2 in this case).

  Implemented by Shinya Hanataka and Ulrich Drepper.

* New codeset conversion modules: IBM-922  (Estonia PC codeset),
  IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
  Contributed by Masahide Washizawa <washi@jp.ibm.com>.

* Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
  <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.

* The LANGUAGE environment variable is now ignored unless the locale is
  changed from the default "C" locale.

* The usual bug fixes.

Version 2.2

* Greg McGary added runtime support for bounds checking using gcc's
  new -fbounded-pointers option.  ix86 target is complete.  PowerPC
  is in progress.

* Thorsten Kukuk added secure mode support to nscd.

* The Berkeley db libraries have been removed.

  Related, the nss_db module is now in a separate package since it
  obviously requires a database library being available.

* Wide character I/O streams implemented by Ulrich Drepper.

* Functions from the extended socket API added by Ulrich Drepper.

* Functions feenableexcept and fedisableexcept to control the
  behaviour of individual exceptions have been added by Andreas Jaeger.

* ldconfig program added by Andreas Jaeger and Jakub Jelinek.

* The resolver code has been updated from bind 8.2.3-T5B which supports
  threads.  The integration was done by Andreas Jaeger, Adam D. Bradley,
  and Mark Kettenis.

  This change could in some situations effect backward compatibility.  Since
  now `_res' is a thread-local instead of a global variable, modifying it
  in one thread does not have any effect in other threads.

  The resolver library was also extended to allow IPv6 as the transport
  protocol for the requests.  This work was done by Stig Venaas.

* Compatibility code for K&R C compilers has been removed from the
  header files.  A ISO C compiler is needed to use the library
  (conforming to either C89 or C99 standard).

* Complete rewrite of the localedef program to support multibyte character
  sets.  Implement handling of ISO 14651 and ISO 14652.  Rewrite strcoll,
  strxfrm, wcscoll, and wcsxfrm functions.  Make isw*() functions work.
  Implemented by Ulrich Drepper.

  Bruno Haible significantly improved the generation and use of the data
  structures for the wide character tables.

* Plural handling in gettext implemented by Ulrich Drepper.

* The utmp daemon has been removed.

* The port to MIPS-Linux has been finished by Andreas Jaeger.

* A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
  and Yutaka Niibe.

* POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.

* POSIX barriers implemented by Kaz Kylheku.

* POSIX spawn function family implemented by Ulrich Drepper.

* POSIX spinlocks are now available.

* Timed wait functions for mutex, rwlock, and semaphores are implemented.

* the configure option --enable-kernel=X.Y.Z allows to strip out
  compatibility for kernel versions before X.Y.Z.  This is currently only
  implemented for Linux.

* the sockaddr_in6 structure changed.  The IPv6 working group added a new
  field sin6_scope_id.  This means that all programs using IPv6 should be
  recompiled.  Don't expect binary compatibility with previous glibc
  versions.

* various conversion modules for IBM character sets contributed by
  Masahide Washizawa.

* IA-64 port by Jes Sorensen and HJ Lu.

Compiling the GNU C Library for Linux/ia64
******************************************

   Please refer to the file INSTALL in the same directory as you found
this file for general information about configuring and compiling
glibc.

   For general inquiries about glibc under Linux/ia64 please use the
following mailing list linux-ia64@linuxia64.org or one of the relevant
glibc mailing lists.

Recommended Tools for Compilation
=================================

   In order for glibc-2.2 to build correctly on the ia64 you need at
least the following versions of the GNU tools (the :

   * The Cygnus toolchain snapshot for the ia64 as of August 4
     including the provided set of patches.  It is however recommend
     you use the October 24 toolchain snapshot or a more recent version.

   OR alternatively you can try the following (the Cygnus toolchain is
   the recommended solution):

   * GCC and binutils, GAS and GNU LD out of CVS from
     sources.redhat.com as of August 28, 2000 or later.  The CVS tree
     may require special patches to work properly on the ia64.

Configuring and compiling GNU Libc for Linux/ia64
=================================================

   The library requires Linux kernel version 2.4.0-test4-000728 or
later to funtion properly. Besides that it support for debug libraries
is currently untested. Hence the following options
are required for configuring the library:

   --disable-debug --enable-kernel=2.4.0

   It is also important that you make sure the library picks up the
appropriate kernel header files, if you do not have recent enough
kernel headers in /usr/src/linux/include, you should use the
--with-headers=<path> option to specify the location.

   As an example I personally use the following options to configure
the library:

   --disable-debug
   --disable-cvs
   --enable-kernel=2.4.0
   --host=ia64-linux
   --enable-add-ons=yes
   --prefix=/usr
   --with-headers=/home/jes/linux/include


Good luck

Version 2.1.3

* bug fixes


Version 2.1.2

* bug fixes


Version 2.1.1

* New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.

* New xdr functions are added; some rpc functions are now 64bit clean.

* Fixed a number of bugs and memory leaks (especially in NIS+ code).

* Fixed known incompatibilities with glibc 2.0.

* New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.

* Optimized a number of functions (especially the ELF dynamic loader).

* Update timezone data files.

* lots of charmaps corrections

* some new locale definitions and charmaps


Version 2.1

* Richard Henderson corrected size of struct timeval on Linux/Alpha to
  conform to POSIX member type requirements.  Symbol versions have been
  adjusted as needed within the library, and for direct use by applications,
  but there is potential for problems if third-party libraries use
  struct timeval as part of their interface.  This does not present
  a problem for X and other "essential" system libraries.

* An additional locale model to support C++ Standard Library locale
  model and probably more was implemented by Ulrich Drepper.

* Eric Youngdale and Ulrich Drepper implemented versioning of objects on
  symbol level.

* Miles Bader provided the `argp' function family to support hierachical
  command line argument parsing, layered on top of getopt.

* strtod accepts new hexadecimal floating-point format from ISO C 9X.

* printf has two new specifiers %a and %A to print hexadecimal flaoting-point
  numbers.

* scanf recognizes the %a and %A format for scanning floating point numbers.

* the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
  information and interfaces for the available integer types.

* about 130 new math functions were added to implement the ISO C9x math
  library.

* the new header <complex.h> contains definitions of the complex math
  functions from ISO C 9X.

* the new header <tgmath.h> defines generic macros to use complex or
  real valued functions.

* Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.

* Andreas Jaeger provided a test suite for the math library.

* Mark Kettenis implemented the utmpx interface and an utmp daemon.

* Ulrich Drepper added character set conversion functions (iconv).

* Optimized string functions have been added.

* The localedata addon is now part of glibc.

* An implementation of profiling shared libraries was added by Ulrich Drepper.

* Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
  daemon for NSS (nscd).

  Missing a better place here are some numbers on improvements.  Under
  Linux 2.1.125 un-tar-ing the kernel sources takes

				  user	system	   wall

    using local files		12.19s	 6.88s	 22.91s

    using NIS			13.92s	 8.91s	 26.34s

    using NIS & nscd		10.37s	 7.34s	 25.30s

    using NIS+			27.57s	30.37s  640.46s

    using NIS+ & nscd           10.25s   7.83s   26.51s

    using NIS & old nscd [1]	13.83s	 8.32s	 29.60s

  Keep in mind that non-namelookup related operations dominate above times.
  It was just a common complain that using NIS+ unpacking the kernel is
  horribly slow.

  [1] The old nscd implementation is not available anymore since it was
  distributed with glibc up to version 2.0.98 and thus is now replaced.

* Tim Waugh provided an implementation of the POSIX.2 wordexp function family.

* Mark Kettenis provided a Hesiod NSS module.

* The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
  and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).

* rcmd can now handle netgroups (Dick Streefland).

* A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
  Bambrough.

* Support for the IPv6 protocol has been added to the socket API, as per the
  latest draft standards.

* Support for Linux 2.2 has been added.

* Interface changes relative to the latest 2.0.x release:

Version 2.0

* GNU extensions are no longer declared by default.  To enable them you
  must define the macro `_GNU_SOURCE' in your program or compile with
  `-D_GNU_SOURCE'.

* The library has changed from using GNU ld symbol aliases to using weak
  symbols where available.  The ELF object file format supports weak
  symbols; GNU ld also supports weak symbols in the a.out format.  (There
  is also now support for other GNU ld extensions in ELF.  Use the
  `--with-elf' option to configure to indicate you have ELF, and
  `--with-gnu-ld' if using GNU ld.)  This change resulted in the deletion
  of many files which contained only symbol aliases, reducing the size of
  the source and the compiled library; many other files were renamed to
  less cryptic names previously occupied by the symbol alias files.
  There is a new header file <elf.h> for programs which operate on
  files in the ELF format.

* Converted to Autoconf version 2, so `configure' has more options.
  Run `configure --help' to see the details.

* The library can now be configured to build profiling, highly-optimized
  (but undebuggable), and/or shared libraries (ELF with GNU ld only).  The
  `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
  `configure' enable building these extra libraries.  The shared library is
  built by default when using both ELF and GNU ld.  When shared libraries
  are enabled, the new library `-ldl' is available for arbitrary run-time
  loading of shared objects; its interface is defined in <dlfcn.h>.  The
  new header file <link.h> gives access to the internals of the run-time
  dynamic linker, `ld.so'.  The shell script `ldd' is similar to the
  application of same name on other systems and it provides information
  about dynamically linked binaries.

* The C library now provides the run-time support code for profiling
  executables compiled with `-pg'.  Programs can control the profiling code
  through the interface in <sys/gmon.h>.  The `gmon.out' files written by
  the GNU C library can be read only by GNU `gprof' (from GNU binutils);
  the support for this file format was contributed by David Mosberger-Tang.

* The math code has been replaced with a math library based on fdlibm from
  Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
  Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
  functions.  The math functions now reside in a separate library,  so
  programs using them will need to use `-lm' their linking commands.

* John C. Bowman contributed optimized ix87 assembler inline functions.

* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
  mechanism similar to that found in Solaris 2.  This is now used for the
  group, passwd, hosts, networks, services, protocols, rpc, ethers,
  shadow, netgroup, publickey, and alias databases.  The `nsswitch.conf'
  file controls what services are used for each individual database.  This
  works by loading shared libraries with names specified in `nsswitch.conf',
  so service modules can be changed or added at any time without even
  relinking any program.  Currently there are the file, db, and NIS based
  NSS services available.

* The new functions `strtoq' and `strtouq' parse integer values from
  strings, like `strtol' and `strtoul', but they return `long long int' and
  `unsigned long long int' values, respectively (64-bit quantities).

* The new functions `strtof' and `strtold' parse floating-point values from
  strings, like `strtod', but they return `float' and `long double' values,
  respectively (on some machines `double' and `long double' are the same).

* Ulrich Drepper has contributed new implementations of the floating-point
  printing and reading code used in the `printf' family of functions and
  `strtod', `strtof', and `strtold'.  These new functions are perfectly
  accurate, and much faster than the old ones.

* The implementation of the POSIX locale model was completely rewritten by
  Ulrich Drepper.  This includes the new programs `localedef' and `locale'
  to compile the POSIX locale definition.

* The former dummy implementations of the strcoll and strxfrm function are
  now replaced by fully functional code contributed by Ulrich Drepper.  The
  collation information comes from the POSIX locale definitions.

* The new header <langinfo.h> defines an interface for accessing
  various locale-dependent data (using the locale chosen with `setlocale').

* Ulrich Drepper has contributed a new suite of functions for operation on
  wide-character and multibyte-character strings, in <wchar.h>;
  and classification and case conversion of wide characters, in <wctype.h>.
  These new functions are conforming to the ISO C, Amendement 1 specification.

* There is now a second implementation of the standard I/O library available.
  It comes from GNU libg++ as was written by Per Bothner, heavily modified
  by Hongjiu Lu and made thread safe by Ulrich Drepper.

* You can now use positional parameter specifications in format strings
  for the `printf' and `scanf' families of functions.  For example,
  `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
  ``Number 6, Mr Jones''.  This is mainly useful when providing different
  format strings for different languages, whose grammars may dictate
  different orderings of the values being printed.  To support this
  feature, the interface for `register_printf_handler' has changed; see
  the header file <printf.h> for details.

* The `printf' and `scanf' families of functions now understand a new
  formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
  to group numbers as indicated by the locale; for `scanf' and friends, this
  says to accept as valid only a number with all the proper grouping
  separators in the right places.  In the default "C" locale, numbers are
  not grouped; but locales for specific countries will define the usual
  conventions (i.e. separate thousands with `,' in the US locale).

* The pgrp functions have been regularized, slightly incompatibly but much
  less confusingly.  The core functions are now `getpgid' and `setpgid',
  which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
  argument) and BSD `setpgrp' (identical to `setpgid') functions are
  provided for compatibility.  There is no longer an incompatible `getpgrp'
  with an argument declared under _BSD_SOURCE; no BSD code uses it.

* The new header file <fts.h> and suite of functions simplify programs that
  operate on directory trees.  This code comes from 4.4 BSD.

* The resolver code has been updated from the BIND 4.9.5-P1 release.
  Parts of the code were heavily modified by Ulrich Drepper to fit in the
  NSS scheme used in glibc.

* There is a new malloc debugging hook `__memalign_hook'.

* There are new typedefs `ushort' for `unsigned short int' and `uint' for
  `unsigned int' in <sys/types.h>.  These are for compatibility only and
  their use is discouraged.

* The `-lmcheck' library to enable standard malloc debugging hooks is now
  done differently, so that it works even without GNU ld.

* New function `euidaccess' checks allowed access to a file like `access',
  but using the effective IDs instead of the real IDs.

* The time zone data files have been updated for the latest and greatest
  local time conventions of the countries of the world.

* The new function `dirfd' extracts the file descriptor used by a DIR stream;
  see <dirent.h>.

* The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
  for formatting floating-point numbers.  They are provided only for
  compatibility; new programs should use `sprintf' instead.  There are
  also equivalent function for the `long double' floating-point type and
  all functions also exist in a reentrant form.

* The new auxiliary library `-lutil' from 4.4 BSD contains various
  functions for maintaining the login-record files (primarily of use to
  system programs such as `login'), and convenient functions for
  allocating and initializing a pseudo-terminal (pty) device.

* Ulrich Drepper has contributed new support for System V style
  shared memory and IPC on systems that support it.

* Ulrich Drepper has contributed several miscellaneous new functions found
  in System V: The `hsearch' family of functions provide an effective
  implementation of hash tables; `a64l' and `l64a' provide a very simple
  binary to ASCII mapping; `drand48' and friends provide a 48-bit random
  number generator.

* Ulrich Drepper has contributed new reentrant counterparts for the
  `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.

* Ulrich Drepper has contributed new, highly-optimized versions of several
  string functions for the i486/Pentium family of processors.

* Ulrich Drepper has updated the Linux-specific code, based largely
  on work done in Hongjiu Lu's version of GNU libc for Linux.
  The GNU library now supports Linux versions 2.0.10 and later,
  using the ELF object file format (i[3456]86-*-linux).

* Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).

* David Mosberger-Tang and Richard Henderson have ported the C library
  to Linux/Alpha (alpha-*-linux).  Richard Henderson contributed the
  dynamic linking support for ELF/Alpha.

* Richard Henderson contributed several Alpha optimized assembler function
  for arithmetic and string handling.

* Ulrich Drepper has contributed a new set of message catalog functions to
  support multiple languages using the <libintl.h> interface, for use with
  his new package GNU gettext.  Translation volunteers have contributed
  catalogs of the library's messages in Spanish, German, and Korean.

* For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
  program and the `catgets' function for reading the catalog files it
  creates.  (The <libintl.h> interface is preferred; we include the
  <nl_types.h> interface using `catgets' only for source compatibility with
  programs already written to use it.)

* New header file <values.h> gives SVID-compatible names for <limits.h>
  constants.

* Various new macros, declarations, and small header files for compatibility
  with 4.4 BSD.

* New function `group_member' is a convenient way to check if a process has
  a given effective group ID.

* When using GCC 2.7 and later, the socket functions are now declared in a
  special way so that passing an argument of type `struct sockaddr_in *',
  `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
  `struct sockaddr *' type, does not generate a type-clash warning.

* New function `error' declared in header file <error.h> is a convenient
  function for printing error messages and optionally exiting; this is the
  canonical function used in GNU programs.  The new functions `err', `warn',
  and friends in header file <err.h> are the canonical 4.4 BSD interface for
  doing the same thing.

* The <glob.h> interface has several new flags from 4.4 BSD that extend the
  POSIX.2 `glob' function to do ~ and {...} expansion.

* New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
  `clearenv' which is used in POSIX.9 is also available.

* New function `getsid' returns session ID number on systems that support it.

* We have incorporated the 4.4 BSD `db' library (version 1.85).  New header
  files <db.h> and <mpool.h> provide a rich set of functions for several
  types of simple databases stored in memory and in files, and <ndbm.h> is
  an old `ndbm'-compatible interface using the `db' functions.  Link with
  `-ldb' to get these functions.

* New macro `strdupa' copies a string like `strdup', but uses local stack
  space from `alloca' instead of dynamic heap space from `malloc'.

* New function `strnlen' is like `strlen' but searches only a given maximum
  number of characters for the null terminator.  `stpncpy', `strndup' and
  `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
  function.

* New function `statfs' in header <sys/statfs.h>.

* The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
  provide convenient functions for operating on blocks of null-terminated
  strings.

* A new suite of functions in <utmp.h> handle all the details of reading
  and writing the utmp file.

* An implementation of the NIS/YP(tm) based NSS service was contributed by
  Thorsten Kukuk.

* Paul Eggert and Ulrich Drepper modified the `strftime' function to be
  completely POSIX compliant and also implemented the extended functionality
  to handle alternate digit representation and alternate era date formats.

* Ulrich Drepper provided an implementation of the `strptime' function
  defined in XPG4.2 which transforms a string into a `struct tm' value.

* Paul Eggert provided the tzselect shell script as part of the timezone
  code.  The shell script makes it easy to select the correct timezone
  specification.

* The implementation of the malloc family of functions is completely replaced
  by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
  The implementation uses the mmap function (if available) and it is
  optimized for the use in multi threaded programs.

* Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
  functions.  This new functionality is usable by specifying a special
  salt string and it is compatible with implementation on *BSD systems.

* Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
  `getsubopt' to handle second level command line options, `bsd_signal'
  to access BSD style `signal' functionality, the obsolete `regexp' style
  expression matcher.

* the `lchown' function is available on system which support this
  functionality.

* The implementation of the shadow password handling function was contributed
  by Ulrich Drepper.

* David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.

* POSIX.1g support was added.  The <sys/select.h> header is available,
  `isfdtype' and `pselect' are implemented.  Craig Metz contributed an
  implementation of `getaddrinfo'.

Version 1.09

* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.

* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
  friends, for parsing /etc/fstab.  This code comes from 4.4 BSD.

* The new function `daemon' from 4.4 BSD is useful for server programs that
  want to put themselves in the background.

* Joel Sherrill has contributed support for several standalone boards that
  run without an operating system.

* `printf', `scanf' and friends now accept a `q' type modifier for long
  long int as well as `ll'.  Formats using these might be `%qu' or `%lld'.

* All of the code taken from BSD (notably most of the math and networking
  routines) has been updated from the BSD 4.4-Lite release.

* The resolver code has been updated from the BIND-4.9.3-BETA9 release.

* The new functions `getdomainname' and `setdomainname' fetch or change the
  YP/NIS domain name.  These are system calls which exist on systems which
  have YP (aka NIS).

* The time zone data files have been updated for the latest international
  conventions.

* The SunRPC programs `portmap' and `rpcinfo' are now installed in
  $(sbindir) (usually /usr/local/sbin) instead of $(bindir).

Version 1.08

* The C library now includes support for Sun RPC, from Sun's free
  RPCSRC-4.0 distribution.  The `portmap', `rpcinfo', and `rpcgen' programs
  are included.  (There is still no support for YP.)

* Tom Quinn has contributed a port of the C library to SGI machines running
  Irix 4 (mips-sgi-irix4).

* The new `lockf' function is a simplified interface to the locking
  facilities of `fcntl', included for compatibility.

* New time functions `timegm', `timelocal', and `dysize' for compatibility.

* New header file <sys/timeb.h> and new function `ftime' for compatibility.

* New header files <poll.h> and <sys/poll.h> and new function `poll' for
  compatibility.

* The error message printed by `assert' for a failed assertion now includes
  the name of the program (if using GNU ld) and the name of the calling
  function (with versions of GCC that support this).

* The `psignal' function is now declared in <signal.h>, not <stdio.h>.

* The library now includes the <sys/mman.h> header file and memory
  management functions `mmap', `munmap', `mprotect', `msync', and
  `madvise', on systems that support those facilities.

* The interface for `mcheck' has changed slightly: the function called to
  abort the program when an allocation inconsistency is detected now takes
  an argument that indicates the type of failure.  The new function
  `mprobe' lets you request a consistency check for a particular block at
  any time (checks are normally done only when you call `free' or `realloc'
  on a block).

* It is now possible to easily cross-compile the C library, building on one
  system a library to run on another machine and/or operating system.  All
  you need to do is set the variable `HOST_CC' in `configparms' to the
  native compiler for programs to run on the machine you are building on (a
  few generator programs are used on Unix systems); set `CC' to the
  cross-compiler.

* The new function `fexecve' (only implemented on the GNU system) executes
  a program file given a file descriptor already open on the file.

Version 1.07

* Brendan Kehoe has contributed most of a port to the DEC Alpha
  running OSF/1 (alpha-dec-osf1).  He says it is 75% complete.

* You can set the variable `libprefix' in `configparms' to specify a prefix
  to be prepended to installed library files; this makes it easy to install
  the GNU C library to be linked as `-lgnuc' or whatever.

* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
  copies a limited number of characters from a string, and returns the
  address of the last character written.

* You no longer need to check for whether the installed `stddef.h' is
  compatible with the GNU C library.  configure now checks for you.

* You can now define a per-stream `fileno' function to convert the
  stream's cookie into an integral file descriptor.

* ``malloc (0)'' no longer returns a null pointer.  Instead, it
  allocates zero bytes of storage, and returns a unique pointer which
  you can pass to `realloc' or `free'.  The behavior is undefined if
  you dereference this pointer.

* The C library now runs on Sony NEWS m68k machines running either
  NewsOS 3 or NewsOS 4.

* The new `syscall' function is a system-dependent primitive function
  for invoking system calls.  It has the canonical behavior on Unix
  systems, including unreliable return values for some calls (such as
  `pipe', `fork' and `getppid').

* The error code `EWOULDBLOCK' is now obsolete; it is always defined
  to `EAGAIN', which is the preferred name.  On systems whose kernels
  use two distinct codes, the C library now translates EWOULDBLOCK to
  EAGAIN in every system call function.

Version 1.06

* The GNU C Library Reference Manual is now distributed with the library.
  `make dvi' will produce a DVI file of the printed manual.
  `make info' will produce Info files that you can read on line using C-h i
  in Emacs or the `info' program.
  Please send comments on the manual to bug-glibc-manual@gnu.org.

* The library now supports SVR4 on i386s (i386-unknown-sysv4).

* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.

* Jason Merrill has contributed a port to the Sequent Symmetry running
  Dynix version 3 (i386-sequent-dynix).

* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
  ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).

* New function `memory_warnings' lets you arrange to get warnings when
  malloc is running out of memory to allocate, like Emacs gives you.

* The C library now contains the relocating allocator used in Emacs 19 for
  its editing buffers.  This allocator (ralloc) minimizes allocation
  overhead and fragmentation by moving allocated regions around whenever it
  needs to.  You always refer to a ralloc'd region with a "handle" (a
  pointer to a pointer--an object of type `void **').

* There is a new `printf' format: `%m' gives you the string corresponding
  to the error code in `errno'.

* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
  or `%[' conversion, but instead of filling in a fixed-sized buffer you
  pass, the `a' modifier says to fill in a `char **' you pass with a
  malloc'd string.

* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
  `FNM_CASEFOLD'.  `FNM_LEADING_DIR' lets a pattern like `foo*' match a
  name like `foo/bar'.  `FNM_CASEFOLD' says to ignore case in matching.

* `mkstemp' is a traditional Unix function to atomically create and open a
  uniquely-named temporary file.

Version 1.05

* The standard location for the file that says what the local timezone is
  has changed again.  It is now `/usr/local/etc/localtime' (or more
  precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.

* The distribution no longer contains any files with names longer than 14
  characters.

* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
  These are set by the new `trusted' and `console' keywords in `/etc/ttys'.

* New functions `ttyslot' and `syslog' from 4.4 BSD.

Version 1.04

* The configuration process has changed quite a bit.  The `configure'
  script is now used just like the configuration scripts for other GNU
  packages.  The `sysdeps' directory hierarchy is much rearranged.
  The file `INSTALL' explains the new scheme in detail.

* The header files no longer need to be processed into ANSI C and
  traditional C versions.  There is just one set of files to install, and
  it will work with ANSI or old C compilers (including `gcc -traditional').

* Brendan Kehoe and Ian Lance Taylor have ported the library to the
  MIPS DECStation running Ultrix 4.

* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
  Tom Quinn contributed the initial code.  The GNU C library can NOT yet be
  made itself into a shared library.

* Yet further improved support for the i386, running 4.3 BSD-like systems
  (such as Mach 3 with the Unix single-server), or System V.

* New function `strncasecmp' to do case-insensitive string comparison
  with limited length.

* New function `strsep' is a reentrant alternative to `strtok'.

* New functions `scandir' and `alphasort' for searching directories.

* New function `setenv' is a better interface to `putenv'.

* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
  function for traversing a directory tree.

* The GNU obstack package is now also part of the C library.
  The new function `open_obstack_stream' creates a stdio stream that
  writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
  formatted output directly to an obstack.

* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
  cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.

* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.

* The new functions `strfry' and `memfrob' do mysterious and wonderful
  things to your strings.

* There are some new test programs: test-fseek, testmb, and testrand.

* Some work has been done to begin porting the library to 4.4 BSD and Linux.
  These ports are not finished, but are a good starting place for really
  supporting those systems.

* `/etc/localtime' is now the standard location for the file that says what
  the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
  This follows the general principle that `/etc' is the place for all local
  configuration files.

* The C library header files now use `extern "C"' when used by the C++
  compiler, so the C library should now work with C++ code.

* The header file <bstring.h> is gone.  <string.h> now declares bcopy,
  bcmp, bzero, and ffs.  (Update: nowadays these functions are declared
  in <strings.h>.)

* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
  function which uses the `merge sort' algorithm, and is said to be
  significantly faster than the old GNU `qsort' function.  Merge sort is
  now the standard `qsort' function.  The new algorithm can require a lot
  of temporary storage; so, the old sorting function is called when the
  required storage is not available.

* The C library now includes Michael Glad's Ultra Fast Crypt, which
  provides the Unix `crypt' function, plus some other entry points.

* The code and header files taken from 4.4 BSD have been updated with the
  latest files released from Berkeley.
