Ah.  My bad.
/backend/prot/win32/socket.c

static void
TranslateSocketError(void) etc.  This puts the value in errno like it is
suppoed to be.  MS recv() does not (I checked) so this is definately a
bug in pipe.c, since it is reasonable for the caller to expect errno to
be set to something.

Also, recv() and read() return completely different error codes :-).  So
any caller has to be careful not to make assumptions about errno.
