1997-09-16 02:14  Ulrich Drepper  <drepper@cygnus.com>

	Implementation of Hesiod NSS module by Mark Kettenis.
	* hesiod/Makefile: New file.
	* hesiod/hesiod.c: New file.
	* hesiod/hesiod.h: New file.
	* hesiod/hesiod_p.h: New file.
	* hesiod/libnss_hesiod.map: New file.
	* hesiod/nss_hesiod/hesiod-grp.c: New file.
	* hesiod/nss_hesiod/hesiod-pwd.c: New file.
	* hesiod/nss_hesiod/hesiod-service.c: New file.
	* sysdeps/unix/inet/Subdirs: Add hesiod.

	* shlib-versions: Add version number for libnss_hesiod.

	* libio/iolibio.h: Remove definition of _IO_* macros.
	* libio/fileops.c: Define close, fstat, lseek, read, and write as
	macros to use __ protected versions.  Use those functions instead
	of _IO_* functions.
	* libio/iopopen.c: Define _IO_close to close.

	* manual/math.texi: Explain the use of the optimizing inline
	functions.
	Describe rand_r function and tell about SysV RNGs in introduction.

	* resolv/res_send.c (res_send): Use socklen_t type for `fromlen'
	variable.

	* string/Makefile (tests): Add noinl-tester.
	* string/noinl-tester.c: New file.
	* string/tester.c: Add more stpcpy tests for constant arguments for
	all short lengths.

	* string/string.h: Always declare __bzero.
	Describe __NO_STRING_INLINES.
	Always include <bits/string.h>.
	* string/bits/string2.h: Add warning about direct use.
	Change __strcpy_small and __stpcpy_small implementation to use
	macros and provide alternative for platforms which cannot do
	unaligned stores.
	* sysdeps/i386/bits/string.h: Don't define anything is
	__NO_STRING_INLINES is defined.
	* sysdeps/i386/i486/bits/string.h: Change __strcpy_small and
	__stpcpy_small implementation to use macros and provide
	alternative for platforms which cannot do unaligned stores.
	* sysdeps/alpha/bzero.S: Define bzero as weak alias of __bzero.
	* sysdeps/generic/bzero.c: Likewise.
	* sysdeps/i386/bzero.c: Likewise.
	* sysdeps/i386/i586/bzero.S: Likewise.
	* sysdeps/vax/bzero.s: Likewise.

	* sysdeps/generic/bits/select.h: Don't use ugly casts to access array.
	* sysdeps/i386/bits/select.h: Likewise.

	* sysdeps/i386/fpu/bits/mathinline.c (__finite): Relax register
	constraints a bit.
	Don't define and test for _BITS_MATHINLINE_H.  Emit warning if used
	directly and not through math.h.

	* sysdeps/i386/i486/atomicity.h: Change return type of compare_and_swap
	to char to get better code.  Fix typo.
	* sysdeps/stub/atomicity.h: Fix typo.

1997-09-14  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/generic/stpcpy.c: #undef stpcpy and __stpcpy.

1997-09-14  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* string/bits/string2.h: Add prototypes to avoid warning.

1997-09-14  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* string/bits/string2.h (strsep): Fix handling of empty REJECT.
	(__strsep_1c): Handle NULL and empty string.
	(__strsep_g): Likewise.

1997-09-13  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* catgets/Makefile (extra-objs): Set this instead of generated.

	* md5-crypt/Makefile (extra-objs): Add all object file variants of
	onlymd5-entry.

1997-09-12  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/generic/sysd-stdio.c (__stdio_read): Fix typo in last
	change.

	* posix/globtest.c: New file.
	* posix/globtest.sh: New file.
	* posix/glob.c: Pretty print preprocessor stuff.
	(glob_in_dir): If PATTERN is not really a pattern still check
	whether it is a real file in the current directory and return
	error if not.
	Reported by Eugene Mamchits <eugin@ips.ras.ru>.

	* libio/fileops.c (_IO_file_sync): Acquire lock before doing the work.
