A "label" is only a part of the fqdn:
<domain> ::= <subdomain> | " "
<subdomain> ::= <label> | <subdomain> "." <label>
<label> ::= <letter> [ [ <ldh-str> ] <let-dig> ]
Yes, each label can only have 63 bytes, but the entire fqdn can be
longer, much longer. And the hostname stored with sethostname() should
be the fqdn of the machine, not just one lalbel (in DNS speak).
