Bug#27427: resolveip fails on hostnames with a leading digit
Patch by Kasper Dupont. No CLA required for this size of patch. "resolveip" program produces incorrect result if given a hostname starting with a digit. Someone seems to have thought that names can not have digits at the beginning. Instead, use the resolver library to work out the rules of hostnames, as it will undoubtedly be better at it than we are. configure.in: See if we need to a library for address lookups. extra/resolveip.c: Don't use silly heuristic to know whether a string is a dotted quad. Instead, pass the whole thing into the resolver and let its smarts do all the work.
