Actually ACT already supports GNAT based on a gcc 3.2 code base it is just
that gcc 3.2 does not have the most up to date GNAT code in it.

You can either go back to gnat-3.15p (which is still going to be missing
some features that
you might want or need) or you can upgrade to GNAT 5.01 by building it
yourself from the CVS sources
http://libre.act-europe.fr/GNAT/

There are directions on how to build it somewhere in  CVS.

It seems scary but just follow them exactly and you will be ok.

Note that whatever version you use I believe there are some tasking issues
with Redhat 9 and GNAT due to the
threading changes RH9.
