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.

1997-03-04 19:14  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/m68k/fpu/__math.h: Update feature tests to use
	__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.

1997-03-04 10:11  H.J. Lu  <hjl@lucon.org>
