        * call.c (joust): Only prefer a non-builtin candidate to a builtin
        one if they have the same signature.

        * cvt.c (build_up_reference): Take DECL parm.  Check TREE_STATIC on

        * decl2.c (get_temp_name): Lose.
        * mangle.c (mangle_ref_init_variable): New fn.
        (mangle_guard_variable): Strip the ref-init header.
        * cp-tree.h: Adjust.
        * decl.c (cp_finish_decl): Add the DECL_STMT after processing the
        initializer.
        (grok_reference_init): Always use DECL_INITIAL.
