    c++: Report invalid id-expression in decltype [PR100482]

    This patch ensures that any errors raised by finish_id_expression when
    parsing a decltype expression are properly reported, rather than
    potentially going ignored and causing invalid code to be accepted.

    We can also now remove the separate check for templates without args as
    this is also checked for in finish_id_expression.

            PR c++/100482

    gcc/cp/ChangeLog:

            * parser.cc (cp_parser_decltype_expr): Report errors raised by
            finish_id_expression.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/decltype-100482.C: New test.
