update from main archive 970202cvs/libc-970203
1997-02-03 02:33 Ulrich Drepper <drepper@cygnus.com> * elf/dl-deps.c (_dl_map_object_deps): Handle multiple AUXILIARY entries. This is still no complete implementation since AUXILIARY entries in other shared objects are not yet handled. * libio/libio.h (_IO_cookie_io_functions_t): Move to C++ protected place. * po/es.po: Update. * po/fr.po: Update. * po/nl.po: Update. * time/Makefile: Better cross-compile support. Avoid test which cannot be run. (CFLAGS-tzset.c): New variable. Overwrite TZDEFAULT value from tzfile.h file. * time/tzfile.c (__tzfile_read): Allow TZDEFAULT start with '/' even in SUID programs. * time/tzset.c (__tzset_internal): If TZ envvar is not set use same default values as in tzfile.c. * elf/dynamic-link.h (elf_get_dynamic_info): Recognize versioning tags. * elf/link.h: Likewise. * elf/elf.h: Add tag definitions and data structures for versioning. 1997-02-03 02:17 Ulrich Drepper <drepper@cygnus.com> * nis/rpcsvc/yp.x (struct ypresp_key_val): There is not stupid "Sun bug". This is the order of elements also used by 4.4BSD. * nis/rpcsvc/yp.h: Likewise. Reported by HJ Lu. 1997-02-02 12:13 H.J. Lu <hjl@gnu.ai.mit.edu> * sunrpc/Makefile ($(objpfx)x%.h, $(objpfx)x%.c): Add "@:" as action. * Makefile (install): Pass installation directories as arguments to ldconfig. 1997-02-02 23:15 Ulrich Drepper <drepper@cygnus.com> * malloc/malloc.c (__after_morecore_hook): New variable. (malloc_extend_top): Call __after_morecore_hook if set. (main_trim): Likewise. * malloc/malloc.h: Add declaration of __after_morecore_hook. Suggested by Marcus Daniels. 1997-02-02 23:00 Marcus G. Daniels <marcus@tdb.com> * malloc/malloc.c (rEALLOc): Protect tsd_setspecific call by #ifndef NO_THREADS. (mallinfo): Likewise. * malloc/malloc.c (__morecore): Make external since it is used in programs. 1997-02-02 15:10 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/statbuf.h (struct stat): Make st_dev field unsigned. 1997-02-01 23:36 Richard Henderson <rth@tamu.edu> * sysdeps/alpha/stxncpy.S ($unaligned) [src % 8 > dst % 8]: Don't use t6 as a temporary; it contains bits we still need in $u_head. 1997-01-31 15:05 John Bowman <bowman@ipp-garching.mpg.de> * sysdeps/i386/fpu/__math.h [__USE_MISC]: Don't declare prototypes using __ prefix. Add prototype for log1p.
