Exporting is somewhat of an advanced topic, so its a shame you have to use this
to learn Ada. But it could have been worse...

Since your main is in Ada, it should be relatively easy. Just use "pragma Export
(C, subprogram_name);" to export subprogram_name to C, as detailed in Annex B,
section 1 of the LRM. If you have parameters to pass, a *thourough* reading of
the implementation advice in Annex B, section 3 of the LRM should tell you how
they will be mapped. If you don't have a dead-tree version of the LRM handy,
there's one online at http://www.ada-auth.org/arm-html/RM-TOC.html .
