I can confirm that, at least partially - for the C++ classes and the method
declarations within them - I have done that work for sufficiently big and complex
collection of the classes, using gcc 3.0 . But I warn you that if you are going
to play with the attributes, then you may meet several annoying errors in gcc,
some of them are hard to locate and fix (not being accustomed with the gcc).
And I didn't deal with the expressions (except of trivial cases in the default
values for the parameters) and the templates.
The documentation (chapter "Trees" in the gcc manual) gives a more or less
suitable starting point, but in many cases you should find a proper macro yourself
(and yes, you may expect that it exists somewhere in tree.h ).
