I received several comments on PM, which I think are of interest to be
answered to a wider audience.

Your impression is right. IMO, neither GNAT nor RTEMS/Ada are in a
usable shape. Something urgently needs to be done about both of them,
otherwise I fear, there will be no future for both of them.

[Try building an ada-enabled cross-compiler and you probably will
experience the reasons why I am saying this yourself.]

Well, I don't want to discourage anybody from using RTEMS. However I
doubt the usability of the FSF's GNAT *in general*. RTEMS/Ada's shape
only is an indirect victim.

I for one had been fighting with the technical impact of GNAT on RTEMS
and the "friendliness" of the GNAT developers for several years.
Meanwhile, I therefore have decided to join the "passive resistance
faction" amongst the GCC developers. Ie. I will not to touch Ada in
RTEMS nor GNAT until GNAT is in a shape to be usable "out of the box".

Check the GCC mailing list archive and you will probably notice what I
am referring to. A group of the GCC developers currently is performing
"passive resistance" against the FSF/GNAT maintainers, others
(comprising leading GCC developers) are actively bashing them.

So, if you think you can change something about this situation, I'd
strongly ask those people who want GNAT+RTEMS/Ada, to take care about
it, to carefully test future GCC/GNAT versions and to contribute bug
