Math.h error "long double" compile flag?

[Eljay Love-Jensen]

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

Are you using GCC/Mingw32 3.3.1?  Or 3.4.0?
