That gives the same error as before.

I was also trying to perform the compilation using the msvc compiler but 
am getting the these errors at the final linking stage.

f2py.py -c --fcompiler=gnu95 --compiler=msvc -lmsvcr90 -m foo foo.f
->Cannot open input file 'msvcr90.lib'

f2py.py -c --fcompiler=gnu95 --compiler=msvc -m foo foo.f
->Cannot open input file 'mingw32.lib'

Where am I going wrong?

Thanks for the help.
