FYI OS/2 compiles fine with both GCC 3.3.5 and 4.3.3. Nasm still doesn't 
work here.
Regression tests fail here with 3.3.5 unless mmx is disabled, pretty 
sure it is a rounding error.

GCC 4.3.3 fails here with a sigsegv. 4.3.3 is still alpha status and 
this is probably an optimization bug.

Both compilers fail regressions here,

All these problems have existed for quite some time so there are no 
recent regressions.
I hope to get a python with sqlite support compiled so I can at least 
occasionally run the Fate suite.
