Thanks for you ideas,
see below for my comments.

Yes, that is why this advise to get a lawer keeps on
coming up, my opinion is not that important later when
the issue comes up in court. 
I keep on bringing up my opinon to try and gain on a
consensus on what to do next.

This is what I brought up on gnu.discuss.misc.
The issue comes back down to deparsing the asts once
they are  in the external form, then the result of
that would only be the input code, andthe code to
deparse  might be a derived work.

I aggree %100 and I have already started this process.
As I pointed out, there are other usages of the
compiler that might fall under this problemm. 
1.The dumping of graphs to graphvis (which is not GPL)
2.The parsing of the original c-dump output using
Gasta.
3.The usage of GCC_XML in CABLE to create function and
typewrapper code.

These other projects and functions of gcc might be
affected by such a desision and really IMHO will have
to be looked into by the FSF independently of my
issue.

Thanks for your advise, before I do any more licencing
I will be sure to submit the idea to FSF before
publishing it.
