So what do we do for openoffice, which breaks when python was compiled with 
fast-math (probably breaking python's math functions). Do we really want to 
add filters for stupid flags? For me the choise has only two viable options. 
1) Completely ignoring the flag; 2) Dieing when it occurs.

I'm affraid that the usage of -ffast-math is that common that option 1 creates 
too many false bug reports. As such we choose to die on it to protect 
ourselves. It prevents us from diagnosing PEBKAC bugs manually.
