Well I am not sure what bugs you are talking about. Actually
it has introduced a number of bugs that cause GNAT to
malfunction. We are working on repairing this now. The first
step was to take all the fixes for critical bugs that had been
done in the 2.8.1 thread, but NOT incorporated into gcc 2.95.
Without these fixes, there were indeed really serious problems
that would make GNAT unusable (many of these were problems that
could also show up in C code).

We are now working on merging the two technologies, and the
first step (merging the 2.8.1 changes into the 2.95 sources
has been completed by Richard Kenner). We are now working on
fixing the remaining bugs that have been introduced that
blow GNAT out of the water, and also on adapting GNAT to the
(in some cases unncessary) changes in the interface between the
front end and back end.

It is being a bigger job that we expected to get GCC 2.9x into
good enough shape to support GNAT, but this is definitely an
important goal.

By the way, we are not aware of any "serious bugs" in 2.8.1
that have been fixed in 2.95 that would affect GNAT. Yes, there
are lots of fixes for g++, but that's another story entirely.
