	for me yes.

	your problem actually has two sides:
	1. when the specified service name ("ftp") was not available,
	   EAI_SERVICE will be returned.  gai_strerror(EAI_SERVICE) is,
	   as defined in RFC, "servname not supported for ai_socktype".
	   this is far less friendly than "unknown service".
	2. when host == NULL and ai_family is not supported by the kernel,
	   EAI_FAMILY will be returned.  gai_strerror(EAI_FAMILY) is
	   "ai_family not supported".  this is not that bad, but not friendly
	   enough IMHO.

	so i tried to address both of them.  I think 1. is the one you've asked.

>IMHO, single printf with gai_strerror should be enough, shouldn't it?

	in general yes, but sometimes the string returned by gai_strerror()
	is cryptic to normal users.
