I'm not sure why the win32 port chose to emulate the SysV semaphore
interface anyway. You could equally well have used the Posix interface
(src/backend/port/posix_sema.c). Or, given Microsoft's NIH tendencies,
you might have needed to write a third implementation of the pg_sema.h
interface ... but it'd likely still be no larger than win32/sema.c ...
