Patch 775605: Cygwin pthread_sigmask() workaround patch Cygwin's pthread_sigmask() implementation appears to be buggy. This patch works around this problem by using sigprocmask() instead. This patch is implemented in a general way so it could be used by other platforms too. If this approach is deemed too risky, then I can work up a patch that just hacks Python/thread_pthread.h for Cygwin. Note that I tested this patch against 2.3c1 under Red Hat Linux 8.0 too. [snip] And finally, I need someone to regenerate pyconfig.h.in and configure with the same versions of the autotools that are normally used by Python. Neal kindly regenerated pyconfig.h.in and configure for me.
