I disagree with your statement that 95% of all useful libraries are in
C++.  More libraries are written in C than in C++.  For example, GNOME
is written in C for the specific purpose of binding easily to other
languages (see http://developer.gnome.org/arch/lang).

Now, if you find a good C++ library which you want to call from Ada,
consider releasing your binding as free software, so that others can
benefit from it.  There already exist many bindings which you can use
without duplicating work.  See http://www.adaworld.com for a list of
free bindings.
