**
** Replacement for a missing or broken inet_ntoa.
**
** Written by Russ Allbery <rra@stanford.edu>
** This work is hereby placed in the public domain by its author.
**
** Provides the same functionality as the standard library routine
** inet_ntoa for those platforms that don't have it or where it doesn't
** work right (such as on IRIX when using gcc to compile). inet_ntoa is
** not thread-safe since it uses static storage (inet_ntop should be used
** instead when available).
