Jeff, your patch:
http://gcc.gnu.org/ml/gcc-patches/2003-01/msg00954.html
Introduced "annotate_with_file_line_column" in treetree.c but didn't
supply an implementation :-(.

I'm currently testing the appended patch and will commit it as obvious
if it passes bootstrap,

Andreas

	* treelang/treetree.c (tree_code_create_function_initial): Replace calls to
	non-existent function annotate_with_file_line_column with
	calls to annotate_with_file_line.
	(tree_code_create_variable): Likewise.
