[Ada] stage2 failure on i686-pc-linux-gnu

[Ada] stage2 failure on i686-pc-linux-gnu

[guerby]

It was working yesterday. Same result with GNAT 3.13p from ALT and ACT, this
is on Mandrake 8.1.

Procedural question: should this kind of report go to gcc@gcc.gnu.org, and/or
be filed as bootstrap in GNATS?

I'd say, send it to gcc@gcc.gnu.org, and only file it as bug if it doesn't
get fixed in a week or so.

FYI, the Ada bootstrap succeeds with current CVS, the unrecognizable insn in exp_vfpt.adb is gone.
Comparison in stage3 still fails, and the Makefile is still confused about gnatmem though.

Thanks for the update. I just checked in the remaining change to disable
gnatmem. Comparison failure in the debug info still needs to be addressed.

There was a thread with "setcc" in the subject in which the
problem was discussed and resolved.
