Okay, where that is found please send a patch.  Examples are
very hard to write because we don't want to clutter them up with
ifdefs as it blurs the use of the library, but if just doing an
include helps.

Well, I recommend that we just use <iostream> and use a simple
kludge to make a fake iostream.  However, this certainly won't work
with both installed.  Gtk-- the library/headers should be safely
tested to figure out which you have and use it.  (The examples
are a different story.)

Havoc is not at this time associated with the Gtk-- project.  He
developed on it some years ago but has since left.  Every so often
he answers a question on the list or gets some renewed interest.
The current maintainers are myself (Karl Nelson) and Guillaume Laurent.

However, you will find the list to be far more helpful that either of
us directly.  :-)
