I take this would be better received:
+static unsigned
+mpd_parse_port(const char *str)
+{
+#ifdef ENABLE_TCP
+ if (*str && !isdigit(*str)) {
+ struct servent *servent = getservbyname(str, "tcp");
+ if (servent)
+ return ntohs(servent->s_port);
+ }
+#endif
+ return atoi(str);
+}

steve suggested authinfo parsing should accept named ports, so for
consistency I made $MPD_PORT accept them as well. I don't care about
this feature to be honest (either in $MPD_PORT or in authinfo file) and
am happy to do whatever you prefer.
