Subject: [PATCH] Check whether we need to declare this; some libc5 systems
 define that

1999-02-10  Martin Baulig  <martin@home-of-linux.org>

	* configure.in (program_invocation_name): Check whether we need
 	to declare this; some libc5 systems define that symbol but do
	not declare it in any header file.
