Finally got it compiled on Cygwin! :)

Victor,

I am still having issue with the "make test" on Cygwin, hence can only do some manual testing:

Output:
>>> info = signal.sigwaitinfo({signal.SIGINT})
^C
>>>
>>> info = signal.struct_siginfo((2, 128, 0, 0, 0, 3))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: signal.struct_siginfo() takes an at least 7-sequence (6-sequence given)
>>> info = signal.struct_siginfo((2, 128, 0, 0, 0, 3, 0))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: signal.struct_siginfo() takes an at most 6-sequence (7-sequence given)
>>> help(signal.struct_siginfo)
