Reiner,

Yikes!  Sorry about that.  I have added a pj_ prefix for all the functions
in geocent.c.  This will be in the next release.

I don't understand.  The geod_ files are for geodetic distance calculations.
I'm not sure what they have to do with pj_init, pj_fwd, pj_inv and pj_transform.
Are you saying that functions like pj_init() don't make it into your library
unless you add the geod files?  I find this very surprising, and I will need
more information on this before I can do anything.

Best regards,
