        * typeck.c (decay_conversion): Convert bitfields to their declared
        types here.  Improve documentation.  Avoid use of cp_convert.
        (default_conversion): Make it static.  Perform integral promotions
        before lvalue-to-rvalue, function-to-pointer, and array-to-pointer
        conversions.
        * init.c (build_init): Remove.
        (expand_default_init): Do not call rvalue.
        * call.c (null_ptr_cst_p): Robustify.
        (build_conditional_expr): Tidy.
        * except.c (build_throw): Do not perform lvalue-to-rvalue
        conversion on operand before initializing temporary.
        * tree.c (convert.h): Include it.
        (convert_bitfield_to_declared_type): Use convert_to_integer, not
        cp_convert.
        (rvalue): Don't convert bitfields to their declared type here.
        * cp-tree.h (build_init): Remove.
        (default_conversion): Likewise.
        * typeck2.c (build_m_component_ref): Do not perform
        lvalue-to-rvalue, function-to-pointer, or array-to-pointer
        conversions here.  Correct error message.
