expr.h (eh_rtime_match_libfunc): New extern declaration.

Browse Source 
Mon Sep 21 17:15:26 EDT 1998  Andrew MacLeod  <amacleod@cygnus.com>
	* expr.h (eh_rtime_match_libfunc): New extern declaration.
	* optabs.c (init_optabs): Set eh_rtime_match_libfunc.
	* except.c (start_catch_handler): Use eh_rtime_match_libfunc.
	* libgcc2.c (__eh_rtime_match): Always return 0 if the matcher is
	NULL. Only include <stdio.h> if inhibit_libc is not defined.
