Pretty unlikely.  This code didn;'t change for ages.  I just checked
against Cygwin 3.2.0 and it also returns success.

Thanks for the STC.  There are actually two long-standing problems,
one in raise, calling pthread_kill even for non-threaded processes,
one in pthread_kill, not checking the signal number.

I'll patch them right away.
