No trouble at all? Ha! You can tell that to the Edison Design Group
people. For some real-life experiences about C++, see the first
article from this staic analysis summit:

It seems EDG are about the only ones with a decent semantic parser for
C++, even they have no chance whatsoever of supporting everything out
there (I'm stuck with a c++ compiler from this obscure little company
called Borland, so I can forget about static analysis tools)

In which case you get a GNU-specific parser, which is not a good
thing. I don't know how much easier it is to build an Ada parser, you
could ask the Bauhaus folks, their tool handles Ada (and is mostly
written in it, too).
