2007-03-16  Manuel Lopez-Ibanez  <manu@gcc.gnu.org>

        * cvt.c (cp_convert_and_check) : Define.
        * cp-tree.h (cp_convert_and_check): Declare.
        * call.c (convert_conversion_warnings): Rename to
        conversion_null_warnings.  The warning for floating-point to
        integer is handled by convert_and_check in convert_like_real.
        (convert_like_real): convert_conversion_warnings was renamed as
        conversion_null_warnings.
        * typeck.c (build_binary_op): Use cp_convert_and_check to warn for
        overflow and changes of value during conversion.

        (cp_parser_namespace_alias_definition): if we find an open brace
        instead of '=', then this is actually a misplaced namespace
        definition.
