Cast the second argument to (struct sockaddr *). i.e.
if (connect(s, (struct sockaddr *)&sin, sizeof sin) < 0) {

RTFM. "man cuserid" says:
DESCRIPTION
The cuserid function is made obsolete by getpwuid.
It is available from the compatibility library, libcompat.
So you need to add -lcompat to the command line, or take the manual
page's advice and use getpwuid (with an argument of geteuid()) instead,
and copy the pw_name member of the returned structure to myuser.
