It definitely does NOT work, significant changes are required
to both GNAT and to GCC for GNAT to compile successfully with
GCC 2.9x. You won't get even the simplest programs running
successfully without a lot of fiddling, and to get a reliable
port, the only practical thing is to wait for the work to get
completed at Ada Core Technologies.

Well I certainly will not disagree with that suggestion :-) and
in fact this is typical of the sort of problem we can help
with very effectively.

But not quite for the above readon :-)
Although that might be the preferred approach in the future,
it is premature to suggest that right now, and the problem
is easily solved in the context of the current release of
GNAT Professional.
