/*
* Replacement for a missing or broken inet_ntoa.
*
* 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).
