I've taught in ADA, back in the late 1990s. As far as I know, gnat (the GNU Ada compiler) is a part of the GCC, so it ought to be possible to include it when building compilers for pandora. Ask PtitSeb, I think.
Then again, I was very happy to leave ADA behind - It was, at least, a cumbersome finicky nitpicky bastard of all the boring bits of Pascal/Modula and military bureucracy.
