        * c-array-notation.c (fix_builtin_array_notation_fn): Update calls to
        build_conditional_expr. 
        * c-parser.c (c_parser_conditional_expression): Create locations for
        EXP1 and EXP2 from their source ranges.  Pass the locations down to
        build_conditional_expr.
        * c-tree.h (build_conditional_expr): Update declaration.
        * c-typeck.c (build_conditional_expr): Add location_t parameters.
        For -Wsign-compare, also print the types.

        * input.c (make_location): New overload.
        * input.h (make_location): Declare.

        * objc-next-runtime-abi-02.c (build_v2_build_objc_method_call): Update
        a call to build_conditional_expr.

        * Wsign-compare-1.c: New test.
        * gcc.dg/compare1.c: Adjust dg-bogus.
        * gcc.dg/compare2.c: Likewise.
