+/* 
+ * Joey Parrish <joey@yunamusic.com>:
+ *
+ * This define is to allow systems without inet_pton() to fallback on
+ * inet_aton().  The difference between the two is that inet_aton() is
+ * strictly for IPv4 networking, while inet_pton() is for IPv4 and IPv6
+ * both.  Slightly limited network functionality seems better than no
+ * network functionality to me, and as all systems (Cygwin) start to
+ * implement inet_pton(), configure will decide not to use this code.
