[f2py] -mno-cygwin

Greetings,

I recently upgraded my compiler to gcc/gfortran version 4.6.0 20101009, 
running under MSYS/MinGW.

Before the upgrade, f2py happily compiled my fortran code into a Python 
module. Following the upgrade, f2py fails with the following message:

Found executable C:\MinGW\bin\gcc.exe
cc1.exe: error: unrecognized command line option '-mno-cygwin'
error: Command "gcc -mno-cygwin -O2 -Wall -Wstrict-prototypes [snip]" 
failed with exit status 1

Given that the "-mno-cygwin" flag is apparently obsolete (and redundant 
under MinGW), how can I force f2py to stop tacking it on when attempting 
to compile a module?

Thanks,

  - Steve
