We have far too many packages that link against libtiff but are not
C++ applications, and it's quite a lot of work to sweep through pkgsrc
to make sure that those applications that link against libtiff, or
that load libtiff via a loadable shared module, are linked using the
C++ compiler.  Therefore, I want to disable the C++ support in the
libtiff.la library and split out the C++ functions into a libtiffcxx.la
and bump the PKGREVISION of the tiff package.

Comments?
