Thanks for the reply!  Sorry to hear you're still using Windows ;-)

Anyway, as far as GNU/Linux allowing multiple versions of GCC, yes,
this is quite possible and common.  However, I've taken the initiative
to compile the entirety of my system from scratch (that is, from the
Linux kernel all the way up to the most obscure utilities), and so I am
managing all software and versioning myself.  This also means that if I
can help it, I'm not going to have multiple versions of programs
hanging around.  ``That way lies madness.''

For completeness reasons (or insanity), I wish to compile GNAT rather
than simply using the binary.  After compiling everything else on my
system, I'm somewhat wary of running software that I didn't type
``make'' to get it working.  Call it a neurosis.

Thanks for the info on AdaCore's current work!  It's encouraging to
know that AdaCore is interested in keeping up with GCC rather than just
focusing on their own product lines.

release is always obsolete!
