Thank you for your answer. I am sorry I was not aware of this rule.
However I have try the following command in the gcc/ directory:

pierre@zenwalk gcc %grep " debug_*" *.h | wc -l
231

And the majority of the result are debug_* functions in header file,
such as extern void debug_tree (tree); in tree.h, extern void
debug_pass (void); in tree-pass.h and many others.
