mingw32 (egcs or not) math

[Stephane Cateland]

I have been trying to port some math stuff with native gcc.
after fiddling with include math.h  I realised that at link stage some 
math function are actually missing.
i noticed : rint    (not much important)
cbrt   more annoying.
(performed several nm -ao *.a | grep "function")

is someone who knows the direct answer
or would tell me where to find source code to build functional libm.a


thanks
