NAME
        AllocRadioButtonNodeA -- allocate a radiobutton node. (v40)

    SYNOPSIS
        struct node * allocradiobuttonnode(uword, tag, ...)
        node = AllocRadioButtonNode(columns, tag, ...)

        struct node * allocradiobuttonnodea(uword, struct tagitem *)
        node = AllocRadioButtonNodeA(taglist)

    FUNCTION
        Allocates a node that can be added to the Exec linked list of
        labels in the radiobutton.  This is the only way to allocate a
        node for this list, you cannot allocate nodes yourself because
        the RadioButton class uses a private node structure.

    INPUTS
        taglist - Attributes for the node, passed onto
            setradiobuttonnodeattrsa().

    RESULT
        node - A node that can be added into the Exec list of labels for
            a RadioButton gadget.
