Subject: [PATCH] Mon Jun 17 19:09:49 1996  Andreas Schwab 
 <schwab@issan.informatik.uni-dortmund.de>

	* Make-dist (+sysdeps): Move wildcard inside loop to avoid consing
	up a huge list just to discard most of it.

	* configure.in (sysnames): Avoid fgrep by using the case shell
	builtin.

	* Makeconfig (config.status): Fix dependency on Implies files.
