We'd much rather have you write a program front end for gcc, then a
slurp up the output of your proprietary front end module.

Yes, the tree stuff remains somewhat stable over time.  I say
somewhat, as we do add new stuff, and flex stuff around some, and the
tree structure isn't usually enough to do a program.  These other
parts sometimes flex as well.  You can compare tree.def from a year to
to ago to the current one, to get a feel for it.
