I'm not, but I can look into it.

This would be a different approach for tackling the same problem.  Question is, do we want the explicit argument types in each function, and more work for make-docfile, or keep things simple for make-docfile and macro-expand the argument name list into appropriate declarations?  The set of macros would basically be parallel to the existing DEFUN_ARGS_* macros, except with names to substitute.

Either leave the arg list unspecified, or we have to do a bunch of casting; I don't think there are any other options...
