One other thought: even if this is safe for HEAD, I think we could
*not* back-patch it into 9.5, because it would amount to an ABI
break on Windows anywhere that pid_t is used in globally visible
structs or function signatures. (Maybe there are no such places,
but I doubt it.) So we'd need to go with the messy-cast solution
for 9.5.
