Thu Sep 28 13:05:54 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
Merge new message handling code from GNU gettext, by Drepper. * intl: New directory. * Makefile (subdirs): Add intl. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Return USER_ENTRY instead of storing it on our stack. * elf/rtld.c (rtld_command): Variable removed. (_dl_skip_args): New variable. (dl_main): Increment _dl_skip_args instead of setting rtld_command. If the link_map for the executable itself is not first in the chain, make it so. * sysdeps/i386/dl-machine.h (RTLD_START): Use _dl_skip_args as count of args to skip. Thu Sep 28 09:20:04 1995 Ulrich Drepper <drepper@gnu.ai.mit.edu> * stdlib/strtod.c (STRTOF): Fix handling of numbers with lots of leading zeroes.
