hash_map iterator error

hi i'm want to use new GNU comipler the problem is with hash_map interator after reading some articles i added some extra macros but the didn't solve the problem compiler seems to do not recognize type template or template and in line hash_map::interator ptr; throws an error: expected `;' before "ptr" here is whole code
