[Proj] SGS85 and WGS84

Using proj4 (C API), should it be possible to move values between WGS84
and SGS85? 'proj -le' lists that the SGS85 ellipsoid is known. But 'proj
-ld' does not list it as a datum/ellipsoid.

It is a little unclear from the docs (to me, but I am thick). At this
time, my user is unclear about exact requirements. I suspect that I will
need to convert from WGS84 to SRS85.

And remember:

It is RSofT and there is always something under construction. 
It is like talking about large city with all constructions finished. 
Not impossible, but very unlikely.
