Well I've been going through A Guide to Network Programming using Internet sockets, by Brian "Beej" Hall, as suggested in the Getting Started section of the Project, and to use the getaddrinfo() function it is necessary to include the <netdb.h> header file. After doing some research, "Adding std=c11 undefines __USE_POSIX macro which guards addrinfo struct in netdb.h" ( where addrinfo is a struct used by getaddrinfo() ). I'm not sure if it is unnecessary for me to be using getaddrinfo() in the first place, but I'm just curious to know whether we are meant to be sticking with the -std=c11 flag
