* Makeconfig (+gccwarn): Add -Winline.

	* hurd/hurdsig.c (_hurd_internal_post_signal): If SS->context is
 	set, avoid abort_rpcs, and use reply and intr ports saved in
 	SS->context.
	* sysdeps/mach/hurd/i386/trampoline.c: Don't set SS->intr_port
 	from SS->context.  Don't clear SS->context.
	* sysdeps/mach/hurd/i386/sigreturn.c: Don't set SS->intr_port when
 	setting SS->context.  If msg_sig_post returns, re-lock and clear
 	SS->context.

Fri May  5 10:37:09 1995  Roland McGrath  <roland@churchy.gnu.ai.mit.edu>

	* mach/Makefile (errsystems.c): Comment out generation rule.

	* sysdeps/mach/_strerror.c: Consider a system unknown if its
 	bad_sub member is null.

	* mach/mig-alloc.c: Add weak alias to non-__ name.
