[tree-ssa] PATCH to remove several -Wno-error targets


My earlier patches made a bunch of these unnecessary.  Thanks to Toon for
checking on the Alpha.

Tested athlon-pc-linux-gnu, applied to tree-ssa.

2003-06-01  Jason Merrill  <jason@redhat.com>

	* Makefile.in: Remove lots of -Wno-error targets.
