Thanks Eljay,
I tried using this:
$ g++ foo.cpp -mno-cygwin -mdll -DBUILD_DLL -O3 -c -fno-exceptions
-ffast-math
and got the same errors as before.
Now in foo.cpp, I had math.h included as:
#include "c:/mingw/include/math.h"
Also the GCC version I'm using is
$ g++ --version
g++ (GCC) 3.3.1 (mingw special 20030804-1)

At this point, I'm not sure whats wrong. Any more clue?
Thanks,

Hi Nirav,
You cannot use "-c" and "-lm" together, as the "-c" makes the "-lm"
semantically void.
You cannot use "-m96bit-long-double" and "-m128bit-long-double" together,
as they are mutually exclusive.
For C++ you should use "g++", for C you should use "gcc".
Other than that...
$ g++ foo.cpp -mno-cygwin -mdll -DBUILD_DLL -O3 -c -fno-exceptions
-ffast-math
...worked for me just fine.
$ g++ --version
g++ (GCC) 3.3.1 (cygming special)

Are you using GCC/Mingw32 3.3.1? Or 3.4.0?
