    PR c++/96442: Improved error recovery in enumerations.

    This patch is a revised fix for PR c++/96442 providing a cleaner
    solution, setting ENUM_UNDERLYING_TYPE to integer_type_node when
    issuing an error, so that this invariant holds during the parser's
    error recovery.

            * decl.cc (start_enum): When emitting a "must be integral" error,
            set ENUM_UNDERLYING_TYPE to integer_type_node, to avoid an ICE
            downstream in build_enumeration.
