I'm trying to figure out the types of function arguments, but bonking.
Please help me understand what is going on here.
void set_nchicken( int n );
For the above function, I have a tree, t, with code FUNCTION_DECL.
TREE_VALUE (TYPE_ARG_TYPES (t)) returns a tree which should be the type of
the first argument. TYPE_NAME of that returns null. I was expecting a
TYPE_DECL who describes the name of the type.
Hrmph.

t is a FUNCTION_DECL. TYPE_ARG_TYPES (t) is, therefore,
meaningless. You want TYPE_ARG_TYPES (TREE_TYPE (t)). See
the documentation in tree.{h,def}.
