However this breaks backward compatibility, since users could
have set it to 0 in their .gprc, etc.

This patch is activating by default some warnings that used to be
only activated when DEBUGMEM>0.
In particular this cause 'make bench' to fail for the debug build
(Olinux-x86_64.dbg).

In any case I do not think it makes sense to change the interface each
time someone would like to silence a warning.
We need a global solution for this, preferably with a better
granularity.

Cheers,
Bill.
