I can tell how I forced my gcc/gnat to work together.
I have redhat-like distribution, and I've got the egcs-1.0.3a source
(recommended). Also I've got the gnat-3.10p source.

1. Unpack egcs sources.
2. Unpack subdir. ".../src/ada" from gnat source into subdir. ".../gcc/"
   under egcs top dir. source.
3. Go into egcs top dir. source.
4. Apply next patch:

5. Do egcs configure procedure.
6. Do make bootstrap
7. Go into ".../gcc" subdir. and perform all steps from
   README.BUILD file from gnat-3.10p source distribution, like:
   make gnattools, make gnatlib, etc.
8. Go back up to top dir. in egcs source.
9. Do make install.

Good luck!
