Could you elaborate further your last statement? Why do you think
gnat3.15p is not so useful with recent GNU/Linux distribution?

Also, does gnat3.15p work well with gcc3.3.3?

If I'm going to bootstrap gnat 3.15p with gnat/gcc3.3.3, wouldn't the
buggy 3.x affect the compilation? Has anyone tried to bootstrap
gnat3.15p with gnat/gcc3.x before?

Honestly, I have compiled thousands of Ada code (previously compiled
with gnat3.15p on Caldera and SuSE) with gnat/gcc 3.3.3 and had no
problems and they run well until this bug box appeared when I tried to
compile dgate.adb. I had no problem compiling GtkAda-2.2.1 at all. And
the GtkAda installed and works perfectly on my SuSE 9.1pro.

Another issue is that gnat3.15p has been out there for a long time and
seems no upgrade from gnat/libre. Do we consider gnat/gcc 3.x an
upgrade?
