Update.
1998-08-03 16:36 Ulrich Drepper <drepper@cygnus.com> * catgets/catgets.c: Use mmap/munmap only is _POSIX_MAPPED_FILES is defined. * catgets/open_catalog.c: Likewise. * iconv/iconv_prog.c: Likewise. * intl/loadmsgcat.c: Likewise. * locale/findlocale.c: Likewise. * locale/loadlocale.c: Likewise. * locale/programs/localedef.c: Likewise. * malloc/malloc.c: Likewise. * elf/elf.h: Fix typo. * math/Makefile: Use $(LN_S) instead of ln. * sysdeps/generic/getpgid.c: Fix return type. 1998-08-01 02:49 -0400 Zack Weinberg <zack@rabi.phys.columbia.edu> * sysdeps/posix/tempname.c (__stdio_gen_tempname): Rename to __gen_tempname and simplify the interface. Strip out the code to do path search and create FILE objects. This function now takes a mktemp() style template and returns either a name or a file descriptor. (__path_search): New function; searches for directories for temp files. * sysdeps/generic/tempname.c: Stub out __gen_tempname and __path_search, not __stdio_gen_tempname. * libio/stdio.h: Prototype __gen_tempname and __path_search, not __stdio_gen_tempname. * stdio/stdio.h: Likewise. * stdio-common/tempnam.c: Use __path_search and __gen_tempname. * stdio-common/tmpfile.c: Likewise. * stdio-common/tmpfile64.c: Likewise. * stdio-common/tmpnam.c: Likewise. * stdio-common/tmpnam_r.c: Likewise. * misc/mkstemp.c: New file. Use __gen_tempname. * misc/mktemp.c: Likewise. * sysdeps/posix/mkstemp.c: Removed. * sysdeps/posix/mktemp.c: Removed. * sysdeps/generic/mkstemp.c: Removed. * sysdeps/generic/mktemp.c: Removed. 1998-08-02 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * configure.in: Check, if door add-on is installed. * config.make.in: Add have_doors. * sunrpc/Makefile: Add HAVE_DOOR define. * sunrpc/key_call.c: Add keyserv/door interface. * sunrpc/svc_unix.c: Call setsockopt only if SO_PASSCRED is defined. * sunrpc/clnt_unix.c: Likewise. 1998-08-02 Andreas Jaeger <aj@arthur.rhein-neckar.de> * inet/netinet/in.h (IN_CLASSC): Correct mask. Reported by Ian Staniforth <I.Staniforth@sheffield.ac.uk> [fixes PR libc/727]. 1998-08-03 10:23 Ulrich Drepper <drepper@cygnus.com> * misc/Makefile: Fix installation problem with --disable-shared. * posix/Makefile: Likewise. 1998-08-02 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * posix/regex.c (re_search_2): Optimize searching for anchored pattern if '^' cannot match at embedded newlines. (regerror): Renamed from __regerror, which it should only be called if _LIBC. 1998-07-31 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sunrpc/svc_unix.c (__msgread): Check setsockopt return value. 1998-07-31 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/generic/glob.c: Remove obsolete cast. 1998-07-31 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Rules (tests): Fix last change.
