Thank you for reporting this. No idea how -DETHERNUT2 went into 
UserConf.mk, but the Configurator will never override this file. Good 
you solved this.

It's always better to get this solved in your code. While in most cases 
warnings can be ignored, there are situations where it really shows a 
potential bug. In any case Nut/OS apps can be compiled without compiler 
warnings and when building the libraries itself warnings are even 
treated as errors.

For malloc include stdlib.h.

The other warning is indeed strange, because arpa/inet.h declares

extern uint32_t inet_addr(CONST char *str);

so inet_addr("192.168.1.1") should not throw a warning.
