If you have to keep supporting the old gdb, you will need to support
two interfaces to gdb. Unless you are importing MI into
4.17.gnat.3.14p-1. If you have no control over 4.17.gnat.3.14p-1, and
supporting that is your primary goal, I don't see what FSF gdb can do
to correct that, ie I see two conflicting goals here.

About readline, there was a conscious design decision to not provide
it with MI, because the editing capabilities would be implemented at a
different level, in the GUI console, not in gdb. With the interpreter
changes the console becomes now a concrete possibility.  BTW, you may
want to take a look at Apple's Project Builder, I don't know what
level of editing they provided with their console.
