GNU Radio uses pthreads on Cygwin, but uses NT threads on MSYS/MinGW.

Could you elaborate on what you want to do?  Would we use pthreads
directly or would we still be using omnithread?  Should we find out
if Pthreads-win32 http://sourceware.org/pthreads-win32 can be used in
GNU Radio?  I would be happy to help if that is what is needed.

I prefer to use GNU Radio on MSYS/Mingw and am willing to put in some
effort to keep it running there.
