I submitted another patch to the POSIX threads code. It is under SourceForge as patch number 533681.
After I saw your patch, I got started thinking...
I don't understand. If Cygwin requires _rtems_ in order that _POSIX_SEMAPHORES be defined, then either Cygwin has a bug here, or Cygwin needs _rtems_ if you want to use real-time gimmicks like semaphores. In either case, I don't think it's Python's place to second-guess the Cygwin team: report it as a bug to Cygwin, or do whatever they recommend to get _rtems_ defined in the Cygwin build.
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.
