I have taken the aa56 routines (by Stephen Mesier et al) and turned them
into a dll.  The source is completely c or c++.
I use them in a program which produces equal altitude circle intersections
from a group of sights and plots them on a world map.
If anyone is interested in these, let me know. The source and executable
are freely available.
