1997-03-08 05:30  Ulrich Drepper  <drepper@cygnus.com>

	* argp/Makefile (routines): Add argp-eexst.
	* argp/argp-ba.c (argp_program_bug_address): Make `const'.
	* argp/argp-eexst.c: New file.  Define exit status variable.
	* argp/argp-help.c (__argp_state_help): Use argp_err_exit_status
	variable instead of always exiting with value 1.
	* argp/argp-pv.c (argp_program_version): Make `const'.
	* argp/argp.h: Declare argp_err_exit_status.
	Patches by Miles Bader <miles@gnu.ai.mit.edu>.

	* locale/programs/localedef.c: Use argp_err_exit_status to
	terminate with correct value.

	__USE_ISOC9X.
	[__USE_ISOC9X]: Define __log2 and __exp2 inlines.
	(fabs): Remove defininition, it is a gcc builtin.
	(sqrt, __sqrt): Remove definition, they have wrappers in libm.
