[f2py] -mno-cygwin

[Pearu Peterson]

Hi,

Could you try removing all -mno-cygwin occurrences from the following files:

  numpy/distutils/mingw32ccompiler.py
  numpy/distutils/fcompiler/gnu.py

to see if this fixes compilations. Let me know if you got it working and what
changes were needed in these files. Then I can prepare the corresponding
patch for numpy.distutils..

HTH,
Pearu
