cvs build problems

[David Edelsohn]

	An updated version of the IBM Haifa scheduler is available for
integration into GCC.  The update includes software pipelining and
additional branch optimizations.  It might have improved some aspects of
the natural loop detection as well, I do not recall.  These changes can
make a noticeable improvement in some types of algorithms.

	Merging in this work probably should be listed as one of the
official "open project" opportunities on the Projects page.
