Hard to give a clear answer on this one since it is spread over time... We do 
not have a complete port of the full Proj.4 library. We usually port parts of it 
on a projection-by-projection basis (usually from volunter work) as the need 
appear. The last projection ported that way was Cassini in 2008.

We are in contact with IGN as well and they gave us material to help us 
implementing the RGF93 projection. We are planning to implement it. My schedule 
is to get EPSG factory to work on geotidy (I mostly finished to port and clean 
the GeoTools 2.x code. I'm now porting the tests and testing), test the 
integration of that code in geotools and after that I will implement RGF93.
