After going through and doing this, it occurs to me that
the API version for GTK+, as we do it currently, is the
major/minor pair, not just the major version number.

There are various approaches to dealing with this:

 a) Ignore it, and worry about it when GTK+-2.2 comes along.
    The worst that happens is that we have 

    /usr/lib/gtk
    /usr/lib/gtk2
    /usr/lib/gtk2.2

 b) Substitute gtk20 for gtk2 above.

 c) Go with a "version number in the path" approach for the
    directories - /usr/include/gtk/2.0/. (But this doesn't   
    help for gtk-config.)

I'm sort of inclined to go with a), but that is probably
just laziness, on my part, since I have it done that way
already.
