$NetBSD: patch-src_tiffread.c,v 1.2 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.  Unlike tiffwrite.c, tiffread.c forgot
to unset the bogus definitions.  The uint16 and uint32 then has to be
redefined correctly.  (ugly hack)
