Did you file a bug report on this? As Ludovic pointed out, it may be a
problem with the gpr file, but it could be something else.

I maintain gprbuild for Debian, so I'd like to resolve this issue.

Unfortunately I don't think it would be that easy; the only way would
be to "downgrade" the ada_cpp example to something that gnat-4.4 can
handle.

To the OP: note that it is *always* possible to interface Ada with C++
even without the new features of GNAT GPL 2009; it just takes more
effort. In the worst case, you wrap the C++ classes and methods in a
C interface and use pragma Import on that C interface. But gnat-4.4
already has some special support for C++, so the worst case is
unlikely.

I don't know. I don't know these people and I don't know whether they
are specifically interested in Ada or just take random Debian unstable
packages and recompile them in Ubuntu (Ubuntu packages do not have a
designated maintainer like in Debian; they all belong to the "Masters
Of The Universe", as they call themselves; "Universe" really means
"everything not on the Ubuntu installation CD-ROM"). I have no idea
what their release coordination looks like and, TBH, I am not really
interested; I already have enough work as it is and a 6-month release
schedule is much too tight for me.

Maybe. That's off-topic for this newsgroup, though.

That's not the problem the OP reported; they said "it runs gnatmake, not
gprbuild".

The problem you reported I also noticed. It is fixed in newer upstream
versions of gnat Pro.

The other way is to wait for the latest upstream gnat Pro to make it
into Debian.

IIUC, that's what the OP *thought* was the problem but it wasn't.

Actually the new features are also in the just-released GCC 4.5.0; the
Ada part is not yet packaged for Debian.
