Update.
1998-02-17 15:10 Ulrich Drepper <drepper@cygnus.com> * elf/dl-load.c (open_path): Use __xstat instead of stat. * localedata/tst-locale.sh: Comment out first test for now. 1998-02-14 14:58 H.J. Lu <hjl@gnu.org> * sysdeps/generic/_G_config.h (_G_HAVE_IO_GETLINE_INFO): Defined as 1. * sysdeps/unix/sysv/linux/_G_config.h (_G_HAVE_IO_GETLINE_INFO): Likewise. * libio/iogetline.c (_IO_getline_info): Renamed from _IO_getline. (_IO_getline): Just call _IO_getline_info. * libio/libioP.h (_IO_getline_info): New declaration. * libc.map (_IO_getline_info, __write): Added. 1998-02-17 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sunrpc/rpc_cout.c (inline_struct): Change typo of plus to const char* to shut up gcc. 1998-02-17 11:37 Ulrich Drepper <drepper@cygnus.com> * eld/dl-open.c (_dl_open): Assign correct value to new->l_global. Patch forwarded by Cristian Gafton <gafton@redhat.com>. * math/math.h: Define M_* constants always as `double' and add new macros M_*l which are of type `long double'. * sysdeps/libm-ieee754/s_cacoshl.c: Use M_*l constants now. * sysdeps/libm-ieee754/s_cacosl.c: Likewise. * sysdeps/libm-ieee754/s_casinhl.c: Likewise. * sysdeps/libm-ieee754/s_catanhl.c: Likewise. * sysdeps/libm-ieee754/s_catanl.c: Likewise. * sysdeps/libm-ieee754/s_clog10l.c: Likewise. * sysdeps/libm-ieee754/s_clogl.c: Likewise. * math/libm-tst.c: Likewise. * sysdeps/i386/fpu/bits/mathinline.h (__M_SQRT2): Don't use _Mdbl, define as long double unconditionally. 1998-02-17 Andreas Jaeger <aj@arthur.rhein-neckar.de> * manual/arith.texi (Old-style number conversion): Correct some typos. 1998-02-16 16:28 H.J. Lu <hjl@gnu.org> * time/Makefile (tz-cflags, CFLAGS-tzfile.c, CFLAGS-tzset.c): Restore. * timezone/Makefile (CFLAGS-tzfile.c, CFLAGS-tzset.c): Deleted.
