 Ok then, the submitter should use gnat-aux. I hadn't realized gcc3-ada
 and gcc34-ada were deprecated; we should wait until after 2011Q4 is
 branched before ripping them (both?) out, but then we should probably
 go ahead and nuke them.
 
 NetBSD 4.0 is still supported, for a while at least. However, if
 gcc34-ada doesn't work, it's probably better to fix gnat-aux for
 NetBSD 4 (assuming anyone ever tries/cares about it) than to spend
 time on a dead end.

 That is the sort of thing that should wait until after the freeze.
