Why not gnat Ada in gcc?

Right, and in the case of Ada, the ACATS regression suite, far more
extensive than anything currently publicly available for C or C++,
will be very helpful. One of the great achievments of the Ada
development is that all such artifacts are freely available (as
for example are all the Ada standards documents, which was not
an easy fight with ISO :-)

As I said earlier, the missing link is to make an easy way of runnig
these tests, and that is one of the jobs on our list!
