What do you mean by "reference"? If you mean the struct symbol *
in the AST. It can point to the function prototype or declaration. It is easy to
find out the symbol is a function or not.
Some thing along the lines of :
if (sym->type == SYM_NODE)
sym = sym->ctype.base_type
if (sym && sym->type = SYM_FN) {
/* sym is a function */
}

You need understand that, each local variable or function start with a SYM_NODE.
SYM_NODE bind a type to a instance of the type. e.g. a variable.
A function is just a SYM_NODE with base type as SYM_FN.
You can also try debug_symbol(), see how it print out the function prototype.
I am about to post a AST inspection patch series. That tool should
help you understand
the AST as well. Stay tuned.
