[Bug tree-optimization/37449] [4.4 Regression] calculix gets wrong answer for -O1 -ftree-pre -ffast-math

I was wrong in the description, calculix does get wrong results when compiled
with "-O1 -ftree-pre -funsafe-math-optimizations" with r137631, and starts
failing with those options sometime between 20080326 and 20080601; I've got a
regression hunt going now.
