I looked more into this while solving some nasty mingw FPU handling
bugs on windows 64. I learnt one thing I did not know about C: you can
define inline static functions in headers, and that's the approach
follows for very short functions. For example, FPU status flag code in
BSD is defined as follows:


static __inline int feraiseexcept(int __excepts);

int fereaiseexcept(int excepts);

we could follow this, maybe - once we solve the inline problem (many
compilers do not support it for C). Having optional, non inline is
important IMHO, for future SSE or other dynamically loaded
implementations (where inline is not an option).
