I'd be interested in seeing what you have, if possible.  Could you post a
link to the list?

I'll try that out when I get a chance, and put the results on the
web.  You should be able to do it, though, by just creating a short .cxx
file that includes tree.h, and run g++ on that.  Remember that the
extension is in the C++ front end, so it won't do anything for c-only
code, unless it is compiled by the C++ compiler.

Things like this are the reason I created this list.

Huh?  I think you might have forgotten to complete this sentence :)

This would certainly be interesting, and could facilitate external
debuggers for the compiler.  For this GCC-XML project, I had in mind to be
able to describe C++ in XML, but we could have both.  If we integrate
something into GCC to dump out its tree representation of the program,
then something else could get the information it needs to generate a C++
program representation in another XML format.  This is adding an extra
stage, though, and the GCC tree would be HUGE in XML.

I'm not sure what you mean by this.  Could you elaborate, please?
