This initial checkin has no changes to any of the libgd code so it can be used as a basis for diffs. It also will not build currently because of this. The PHP gd checks need to be incorporated along with a bit of other config magic. It also shouldn't break the build and will only take effect if you use --with-gd=php right now.
