Update.
1998-11-05 1998 H.J. Lu <hjl@gnu.org> * libio/iofgets.c (_IO_fgets): Don't report error if something was read in and errno is set to EAGAIN. * libio/iofgets_u.c (fgets_unlocked): Likewise. 1998-11-05 Philip Blundell <philb@gnu.org> * sysdeps/unix/sysv/linux/net/if_packet.h: Don't include kernel header; it defines too much. Provide a local definition of struct sockaddr_pkt and a comment advising against its use. 1998-11-06 1998 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * extra-lib.mk: Avoid empty include list. 1998-11-04 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * extra-lib.mk: Add support for $(lib)-shared-only-routines. * elf/Makefile (libdl-routines): Add dlopenold only if doing versioning. (libdl-shared-only-routines): New variable. 1998-11-06 Paul Eggert <eggert@twinsun.com> Don't invoke localtime_r or gmtime_r unless it's the GNU C library's localtime_r and gmtime_r; there are too many buggy implementations of localtime_r and gmtime_r out there, and it's not worth keeping track of all the different bugs. * time/mktime.c (__EXTENSIONS__): Remove. (<unistd.h>): No need to include. * time/strftime.c: Likewise. * time/mktime.c (_POSIX_THREAD_SAFE_FUNCTIONS, HAVE_LOCALTIME_R): Remove. (my_mktime_localtime_r): Renamed from localtime_r; all uses changed. Base it on localtime unless _LIBC. * time/strftime.c (my_strftime_gmtime_r): Renamed from gmtime_r; all uses changed. (my_strftime_localtime_r): Renamed from localtime_r; all uses changed. Base them on localtime/gmtime if not _LIBC. 1998-11-07 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/isastream.c: Always return 0 unless it is an invalid file descriptor. This makes this function actually usable. Proposed by Mark Kettenis <kettenis@phys.uva.nl>.
