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.
