On glibc dist `T_OPT` macro defined inside `/usr/include/arpa/nameser_compat.h` file and
looks as
```
#define T_OPT ns_t_opt
```
Inside Alpine dist also exist file `/usr/include/arpa/nameser_compat.h` but content of
this file
```
/usr/include # cat /usr/include/arpa/nameser_compat.h
#include <arpa/nameser.h>
/usr/include #
```
Is need use `nameser_compat.h` file?
