I just realize that the synopsis port of opencxx already contains
a change to deal with this GNU extension. May be we should try to
merge the appropriate parts back into 'mainline' ? Let me know if
I can help...

On an unrelated note: as you know I'm quite interested into the efford
to separate the different opencxx layers.
As I don't have any theoretical background in compiler / parser techniques,
I'm wondering about the nature of all the ptree related business:
As far as I understand only the very first steps are related to a
parse tree proper. Already the construction of things like 'PtreeNamespaceAlias'
nodes belongs into the 'syntax tree' domain, right ?

I'm asking because I have some difficulties drawing a clear line as to
what the AST I use in synopsis should look like. Right now I only manipulate
declarations, but I can imagine at some point to be more flexible and
provide scripting access to the parsed source code and thus similar to
opencxx's goals provide some means to do meta programming.

Any thoughts ?

Regards,
		Stefan
