Currently the geodesic functions are not exported from proj.dll, nor
(I think) are they even built into the DLL.   I'm a bit hesitant to treat
them as part of the support PROJ.4 API since they are quite distinct
from the core of PROJ.4.  The geod_* functions also depend on global
variables which is not a pattern I'm keen on setting in stone.
