If that one person is me, then I have been trying to build gnat-3.10p with
the gcc2 test snapshots lately.  My early attempts at building with egcs
were not successful and I did not look into them vey far since I needed to
test egcs on non-Ada platforms at the time.  gnat-3.10p + testgcc-970803
seems to work OK except for a configuration problem in which a variable in
the generated ada/Makefile (target_alias) does not get substituted
correctly.

I may have some time next week to try this again.  I have been testing to
the sparc-rtems cross target on a linux box.

I did not investigate much but it seemed that the egcs reorganization
compared to gcc 2.7.2.x may have broken something.  I need to try this all
again to confirm it though.

egcs is a bit father along now.  Perhaps it time for me to dust off
egcs+gnat.

That's the only way to do it.
