Please don't play horrible tricks with macros!.  Notice how I assumed you
were not allowing modification of input_pointer when I could only see the
call to the hook.  You ought to be able to just

#define md_parse_name  some_function_or_other

NULL pointer means something...  Which ought to remove the need for an
enum to just say "this is a symbol without fancy @GOT etc. relocations"

Sure, but a lot of local syms are just branch targets in code.
