Update.
1997-10-29 21:20 Ulrich Drepper <drepper@cygnus.com> * libio/strops.c (_IO_str_seekoff): If mode is zero and the read/write pointers are tied set mode according to current stream mode. * include/features.h [_GNU_SOURCE] (_POSIX_C_SOURCE): Define to 199506L. Define _XOPEN_SOURCE to 500 if _POSIX_C_SOURCE is defined. * manual/creature.texi: Describe this. * manual/socket.texi: Describe connect, accept, send, sendmsg, sendto, recv, recvfrom, and recvmsg as cancelation points. * sysdeps/unix/inet/syscalls.list: Add __libc_* names for these functions. 1997-10-17 Andreas Jaeger <aj@arthur.rhein-neckar.de> * Make-dist (try-sysdeps): Don't look for stub files anymore. * manual/maint.texi (Porting): Remove another reference to stub directory. * sysdeps/unix/bsd/sun/sethostid.c: Include stub version from generic subdir. * sysdeps/unix/sysv/irix4/reboot.c: Likewise. * sysdeps/unix/sysv/irix4/swapon.c: Likewise 1997-10-29 03:54 Ulrich Drepper <drepper@cygnus.com> * resolv/nss_dns/dns-host.c: Change variable pointed to by h_errnop in all error cases (PR 244). 1997-10-29 00:56 Ulrich Drepper <drepper@cygnus.com> * posix/glob.c: Fix handling of expressions like "*/" (PR 325). Optimize by using mempcpy. 1997-10-17 Andreas Jaeger <aj@arthur.rhein-neckar.de> * po/Makefile ($(mo-installed)): Don't fail during installation if files don't exist (might happen if msgfmt doesn't exist) (PR 328). Suggested by Wolfram Gloger <wmglo@dent.med.uni-muenchen.de>. 1997-10-24 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/generic/bits/errno.h (ENOMSG): Define it. Pointed out by Klaus Espenlaub <kespenla@hydra.informatik.uni-ulm.de> (PR libc/259). 1997-10-28 17:40 Ulrich Drepper <drepper@cygnus.com> * sysdeps/libm-ieee754/s_cbrt.c: Testing the returned exponent for zero isn't enough to determine illegal arguments. * sysdeps/libm-ieee754/s_cbrtf.c: Likewise. * sysdeps/libm-ieee754/s_cbrtl.c: Likewise. 1997-10-28 17:14 Ulrich Drepper <drepper@cygnus.com> * manual/filesys.texi (S_ISVTX): Describe that it is available with _BSD_SOURCE only. Reported by Jochen Hein <jochen.hein@delphi.central.de>. 1997-10-28 04:26 Ulrich Drepper <drepper@cygnus.com> * time/tzfile.c (__tzfile_compute): Use negated value of offset for timezone variable. * time/tzset.c (tz_compute): Likewise. Reported by Erik Troan <ewt@redhat.com>. 1997-10-28 02:51 Ulrich Drepper <drepper@cygnus.com> * manual/filesys.texi: Correct prototype in readdir_r description. Reported by Jim Meyering <meyering@eng.ascend.com>. 1997-10-27 Andreas Jaeger <aj@arthur.rhein-neckar.de> * math/libm-test.c (cbrt_test): Add test for cbrt(0.970299). 1997-10-26 19:39 Zack Weinberg <zack@rabi.phys.columbia.edu> * stdlib/l64a.c: Produce a useful result for n < 0. * stdlib/a64l.c: Use unsigned type for working variable. * manual/string.texi (general): Grammar, typo, overfull fixes. (strlen): Insert warning about sizeof(char *). (a64l, l64a): Make documentation agree with implementation. * libio/iofdopen.c: Use _IO_FILE_complete, not _IO_FILE_plus. * posix/unistd.h: Add prototypes for __pread, __pread64, __pwrite
