Except that looking at the linker error messages, the reference to
inet_ntoa was in libresolv.  So there isn't anything that INN can do at
the level of including header files; libresolv apparently expects
something on the system to be providing an inet_ntoa library function.

(Checking, all INN source files that call inet_ntoa appear to already
include <arpa/inet.h>.)
