That is correct, AIX 4.2.1, 4.3.3 and 5.1.

inet_ntoa is part of libc.a (on AIX 4.2.1 anyway).  The man page
contains some conflicting information, though:

"All applications containing the inet_ntoa subroutine must be compiled
with _BSD set to a specific value. Acceptable values are 43 and 44.
In addition, all socket applications must include the BSD libbsd.a

I would suggest:
a) Adding -lbsd to CFLAGS
b) Installing all of the bos.adt filesets from your distribution media.

After each you must run "make distclean" re-run "./configure".

If those two things don't work please send me the config.h and
config.log files generated by running "configure" and the output of

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
