Subject: Set different exit codes when exiting from different places in the
 test

2006-03-12  Christian Persch  <chpe@cvs.gnome.org>

	* configure.ac:
	* m4/gecko.m4:

	Set different exit codes when exiting from different places
	in the test program, so we can see the cause of the failure
	in config.log.
