Eek.  Ok, so it's generating wrong code somewhere.  This is for
m68k, right?  At least on Alpha it bootstraps; the annoying fortran
array thing is keeping me from running interesting benchmarks
though. :-P  Gotta fix that soon.

I've got some improvements I want to make this evening; perhaps
I'll find the bug by inspection, or maybe it'll just go away 
with the simplifications.  We'll see.  ;-)

At any rate, we should be able to find the bug via differences in
genrecog.s between egcs & egcs+patch.
