Last time I heard, Ada is not a release criterion for gcc. As I understand
it, this means that the gcc version, even if GMGPL, can be in any state. It
could be perfectly ok yesterday, and today be broken in subtle ways, and
this wouldn't alter the gcc releasing schedule.

True, Ada is not a release criterion, but GCC _is_ stable, because
AdaCore still follows the rules of development in GCC. They merge most
of their changes during Stage 1; in Stage 2 and Stage 3, only bug fixes
are accepted into the compiler. So, GCC 4.1 is quite useable and
appropriate for most purposes; Robert Dewar himself confirmed so,
verbally, during FOSDEM.

It's for this reason, coupled with the fact that AdaCore endorsed versions
use 3.4.6 as backend and not 4.x, and with the fact that gnat is enduring
heavy changes due to the addition of 2005 features, that I hold very low
expectatives on the gcc-gnat, for the time being.

Yes, GNAT Pro and GNAT GPL still use the 3.4.6 backend. There were
glitches in GCC 4.0 due to the introduction of tree-ssa, but these are
now resolved in 4.1.
