I never said that this was a mac-specific problem. It affects all  
position-independent code generation on x86.

Also, via-C compilation has other slight differences from fasm  
compilation, like for example the need for prototypes for FFI- 
imported functions. Having those things change implicitly with -O has  
led to confusion in the past; having them change implicitly on some  
platforms but not on others is even worse.
