I have no MSVC. In that sense it is not verified in fact, and I hope
those who knows well would kindly comment on it.

However, it appears that pg_config.h is not created through
configure, but just copied from pg_config.h.win32 in those
compilers and thus HAVE_CRTDEFS_H will not be defined.
So, I think this code fragment will not be enabled in
_MSC_VER < 1400

In addition, the code fragment should have no harm as far as they
have crtdefs.h.
(Again, this is I think it should, and not tested with real tools.)
