My apologies, I didn't mean to attack.  I tried it, and it failed
building Ada.  That's all I meant.

If there is an up to date patch, I'm happy to review it if it would
help.  But perhaps an Ada maintainer would prefer to do the review, I
don't know what the usual policy is as I've never approved an Ada patch.

I have a patch ready to go which would use C++ in stages 2 and 3.  I
can't propose that patch right now because it fails when building Ada.
If we get Ada fixed, I will propose it.
