configure.in (make_compare_target): Test for GNU cmp and set this variable appropriately.

Browse source 
2003-04-25  Phil Edwards  <pme@gcc.gnu.org>

	* configure.in (make_compare_target):  Test for GNU cmp and set this
	variable appropriately.
	* Makefile.in (compare, compare3, compare4, compare-lean, compare3-lean,
	compare4-lean): Rename actual targets to slowcompare*.  New compare*
	targets depend on names based on make_compare_target.
	* configure:  Regenerated.
