Krzysztof,
Both are defined little earlier in dns.c:
=
/* A list of DNS security features follows */
#define LWIP_DNS_SECURE_RAND_XID1
#define LWIP_DNS_SECURE_NO_MULTIPLE_OUTSTANDING 2
#define LWIP_DNS_SECURE_RAND_SRC_PORT 4

& LWIP_DNS_SECURE_RAND_XID are defined, so why are you defining them?

I have an error compiling dns.c because of LWIP_RAND function is not
defined.
I've checked git log and looks like this function is optional.
Is there any reason why it necessarily has to be used in dns.c?
