1352 * c-parser.c (c_parser_objc_at_property_declaration): Recognize
1353 RID_ASSIGN, RID_COPY, RID_RETAIN, RID_READWRITE and RID_NONATOMIC.
1354 Do not use objc_set_property_attr, but use local variables
1355 instead. Detect repeated usage of setter, getter and ivar
1356 attributes. Improved error processing when a setter name does not
1357 end in ':'. Do not check for CPP_CLOSE_PAREN after we determined
1358 that the token is a keyword. Updated call to
1359 objc_add_property_declaration.

1367 errors. Added comments.
