I wish I was :(  It may be a misunderstanding on my side, but I have
seen function duplication in treelang/treetree.c that merely call
abort.  Previously I had to fix other link errors for treelang's front
end that essentially did the same thing: create an empty function in
treetree.c.

There was a thread discussing this issue recently:
http://gcc.gnu.org/ml/gcc-patches/2003-03/msg01444.html

Perhaps treelang should be changed to use language hooks or generate
GIMPLE or ... something, I don't know.
