 * 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).
