Just an added note here: check the NGS site for full precision online
geodesic computations:

http://www.ngs.noaa.gov/TOOLS/Inv_Fwd/Inv_Fwd.html

FORTRAN sources are also there.  Note, I f2c'ed the nucleus of this

now debugging.  A reference to a copy of the Vincenti algorithm that
the procedures are based upon is also at that site.
