Hi Arnaud, it's nice to see you on c.l.a.

How would you recommend to solve this problem?

I would tend to carefully select a "known good" combination of the
GNAT front-end and GCC back-end, port ASIS to it, and stick with it
until a new "known good" combination comes out.  The problem is, I
don't know if a "known good" combination even exists today, apart from
trusty old GNAT 3.15p and GNAT Pro.  Since you seem to think so little
about GCC 3.3, would you recommend 3.4 instead?  I suppose HEAD (the
future 3.5) is too prone to the moving target syndrome.

And what would be the best way for Martin to help in a way ACT can
use?
