When compiling send_arp.c the compiler warns about some functions and then
bombs out due to -Werror:
In file included from /usr/local/include/libnet.h:124,
from send_arp.c:37:
/usr/local/include/./libnet/libnet-functions.h:1840: warning: function
declaration isn't a prototype
/usr/local/include/./libnet/libnet-functions.h:1862: warning: function

....Setting CFLAGS w/o -Werror clears up the problem:

-Wcast-qual -Wcast-align -Wbad-function-cast -Winline
