Update. cvs/libc-ud-970714
1997-07-14 23:37 Ulrich Drepper <drepper@cygnus.com> * inet/getnameinfo.c: Pretty print. Correctly enlarge buffers. * login/programs/utmpd.c: Use _() instead of gettext(). * nis/nss_nisplus/nisplus-hosts.c: Optimize some uses of stpcpy away. * nis/nss_nisplus/nisplus-network.c: Likewise. * nis/nss_nisplus/nisplus-proto.c: Likewise. * nis/nss_nisplus/nisplus-rpc.c: Likewise. * nis/nss_nisplus/nisplus-service.c: Likewise. * sysdeps/alpha/fpu/bits/mathinline.h: Only define functions if __OPTIMIZE__. * sysdeps/powerpc/bits/mathinline.h: Likewise. * sysdeps/i386/fpu/bits/mathinline.h: Define ISO C9x comparison function always. * sysdeps/m68k/fpu/bits/mathinline.h: Likewise. * sysdeps/stub/bits/mathinline.h: Add conditionals to show how it should look like in real files. * sysdeps/generic/bits/select.h (__FD_ZERO): Don't use memset to prevent prototype trouble, use simple loop. * sysdeps/i386/bits/select.h [!__GNUC__] (__FD_ZERO): Likewise. * sysdeps/mips/mips64/Implies: Imply ieee754. * sysdeps/unix/sysv/linux/Makefile: Make sure bits/syscall.h is installed. * sysdeps/unix/sysv/linux/sys/syscal.h: Pretty print. 1997-07-14 00:25 Ulrich Drepper <drepper@cygnus.com> * sysdeps/stub/bits/stdio_lim.h: Unify with standalone version. * sysdeps/standalone/bits/stdio_lim.h: Removed. Patch by Zack Weinberg <zack@rabi.phys.columbia.edu>. 1997-06-22 Paul Eggert <eggert@twinsun.com> * time/strftime.c (strftime): Use tm_zone if available, even if _LIBC. * time/tzfile.c (__tzstring): New decl. (__tzfile_read, __tzfile_default): Set __tzname to permanent strings. (__tzfile_default): First two args are now const char *. * time/tzset.c (__tzstring): New function. (tz_rule): Name is now const char *. (struct tzstring_head): New type. (tzstring_list, tzstring_last_buffer_size): New static vars. (__tzset_internal): Time zone names are now permanent, not temporary.
