I have noticed that compiling with pgcc-1.1.3 and flags

	-O2 -fcompare-elim -fswap-for-agi

can produce wrong code. In the specific case that I encountered,
pgcc-1.1.1 produced correct code. I will try to find a small example
where pgcc goes wrong. Nothing is crashing, but my chess program finds
different moves, maybe even better ones :)
