The errno values are correct (they're #defined in win32.h), it's just
that the system supplied strerror() doesn't know about them.

From what I can see, there are a couple of places in postmaster.c that
uses it, and that's it. And it's all non-socket related. So I think
we're safe there.

Patch coming up shortly :-)
