I agree with Tim (and Martin) that this is a Cygwin (i.e., newlib) issue and should not be "fixed" or worked around in Python. Would you be willing to submit the attached (untested) patch to newlib after giving it a spin? I think that Rob Collins forgot to add this missing #define when he implemented Cygwin semaphore support. If you wish, I can post to cygwin-developers to verify.
