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.
1997-09-12 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/m68k/m68020/atomicity.h: New file.
1997-09-15 05:11 Ulrich Drepper <drepper@cygnus.com>
* posix/Makefile (distribute): Add globtest.c and globtest.sh.
Compile and run globtest if not cross-compiling.
* 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.
* libio/ioseekoff.c (_IO_seekoff): Likewise.
* libio/ioseekpos.c (_IO_seekpos): Likewise.
1997-09-13 18:06 Ulrich Drepper <drepper@cygnus.com>
* configure.in: Prevent configuration for unsupported platforms.
1997-09-13 04:07 Ulrich Drepper <drepper@cygnus.com>
* elf/rtld.c (dl_main): Make sure we always have a file argument by
testing for < 2 arguments after recognizing the options.
