This is obvious in retrospect but it was a pain in the rear and took  
me a day to find out. The Intel Core Duo processors have SSE2 and  
these also need to be unmasked for floating-point exceptions to be  
trapped. Simply unmasking x87 is not enough.

I'll fix this up, rebuild HiPE and re-run all the tests. If  
everything goes well then I'll generate the patches.
