We are having problems compiling source from cvs:
- seems that ptw32_semwait.c was not added to the cvs
- PAPCFUNC isn't declared when _WIN32_WINNT isn't declared implement.h:449
- in pthreads_cancel.c:179, the thread->cancelLock isn't unlocked when
WaitForSingleObject returns anything else than WAIT_TIMEOUT (if it terminates
earlier during pthread_cancel)
