Your patches just add "defined(_LP64)" to the files.  If they worked
on alpha or sparc64 already, then your change has no effect for those
platforms.  If they didn't work on those other 64-bit platforms, then
these changes got them working at last.  In either case, we won't need
to bump the PKGREVISION for the tiff package since it doesn't affect
any existing binary packages.

Does our gcc not define __LP64__ as a preprocessor macro by default
on 64-bit machines?  Is _LP64 in fact the correct macro to check?  We
need to be sure before we make this change.  Perhaps double check on
