$NetBSD: patch-src_tiffwrite.c,v 1.1 2012/07/29 12:52:55 marino Exp $

Both ocaml/caml/config.h and tiff.h define int32, uint32, etc.
The workaround of this name polution is to intentionally overwrite the
first caml definition with a garbage macro before tiff.h is included and
then unset it after the include.  After tiff version 4.0.1, the same hack
has to be applied to 64-bit types
