Probably because Micro$haft works with Intel when they write their buggy
compilers?? Someone smart needs to dissassemble it, and copy the optimizing
code into egcs, or egcs needs to be done with Intel/AMD's engineers, then we
could have the best compiler stability/optimization wise, and advance
Linux/UNIX even more.
