        Implemented fast enumeration for Objective-C.
        * c-parser.c (objc_could_be_foreach_context): New.
        (c_lex_one_token): Recognize RID_IN keyword in a potential
        Objective-C foreach context.
        (c_parser_declaration_or_fndef): Added parameter.  Accept
        Objective-C RID_IN keyword as terminating a declaration; in that
        case, return the declaration in the new parameter.
        (c_parser_extenral_declaration): Updated calls to
        c_parser_declaration_or_fndef.
        (c_parser_declaration_or_fndef): Same change.
        (c_parser_compound_statement_nostart): Same change.
        (c_parser_label): Same change.
        (c_parser_objc_methodprotolist): Same change.
        (c_parser_omp_for_loop): Same change.
        (c_parser_for_statement): Detect and parse Objective-C foreach
        statements.
        (c_parser_omp_for_loop): Updated call to check_for_loop_decls().
        * c-decl.c (check_for_loop_decls): Added parameter to allow ObjC
        fast enumeration parsing code to turn off the c99 error but still
        perform checks on the loop declarations.
        * c-tree.h (check_for_loop_decls): Updated declaration.
        * doc/objc.texi: Document fast enumeration.

        variables.
