I get a parse error with all permutations of INT funcf ARGS((char *)); and
STATIC int abc;.  Actually, I don't have the impression that STATIC int
abc; is relevant; it is the use of ARGS that it does not seem to like.

We can look into it.  But is it actually blocking what you want to do?  As
long as you are only interested in matching and transforming function
definitions, not function prototype declarations, the problem should not
have any impact.
