1998-11-09 18:16 Ulrich Drepper <drepper@cygnus.com> * math/complex.h: Include bits/mathdef.h to get __NO_LONG_DOUBLE_MATH is needed. Don't define long double functions if __NO_LONG_DOUBLE_MATH is defined. Don't define `complex' but instead `_Complex'. The later is the reserved keyword. * math/bits/cmathcalls.c: Define _Mdouble_complex_ using _Complex, not complex. 1998-11-07 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * manual/libc.texinfo: Remove colon from category name. * manual/Makefile (dir-add.info): Likewise. 1998-11-07 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * configure.in: Avoid autoconf bug. 1998-10-28 H.J. Lu <hjl@gnu.org> * posix/getopt.h: Add "__" to arguments in prototypes. 1998-11-05 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 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. 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.
