Subject: 2000-10-24	Ralf Corsepius <corsepiu@faw.uni-ulm.de>

	* Makefile.am, acinclude.m4, configure.in: Introduce GNU
	canonicalization to libfs/.
	The approach is currently a bit of a hack as GNU canonicalization
	does not support the per-BSP build some of the other directories
	require.  As more of the tree is converted, this will become less
	of an issue.
