This change fixes a bug where exiting a crash signal handler on Windows after adding the signal to uc_sigmask, but not correcting the CPU state would cause the signal handler to loop infinitely, causing process hang Another issue is that very tiny programs, that don't link posix signals would not have their SIGILL / SIGSEGV / etc. status reported to Cosmo's bash shell when terminating on crash. That's fixed by a tiny handler in WinMain() that knows how to map WIN32 crash codes to the POSIX flavors.
