As of Gnuastro 0.19, we still don't recognize the "International Celestial Reference System" or ICRS (which is the IAU approved coordinate system; unlike FK5; that we do support!).

A nice review of ICRS in relation to FK5 and J2000 is given in Feissel and Mignard 1998. In their Figure 1, they show the pole positions in relation to each other.
We should be able to use these pole positions to convert ICRS to 'eq-j2000' and from that, to all the other coordinate systems that are currently recognized.
