I think this is because configure.ac doesn't check for inet_ntop in
libnsl (in Solaris 11.2 inet_ntop and inet_pton are in libnsl)
configure.ac checks for these function in libresolv only.

Yes, if I do not define NO_INET_NTOP/NO_INET_PTON the build is successful
as libnsl is linked - in configure.ac there is 'NEEDS_NSL = YesPlease'
for SunOS'es.
