   In my opinion, separating the C++ front-end from gcc is pointless.
   What you get is more or less the parser, and the g++ parser is not
   something you want to use unless you really have to.  There are a
   number of other good C++ parsers - I'd consider those first if I
   needed one for a project.

any particular recommendations?

btw, is the undesirability of the gcc C++ parser related to its
implementation or to its interface (or both)?  if the implementation is
bad but the interface is ok, perhaps over time the code will change so
that both are ok.
