+ *	This inet_aton() function was taken from the GNU C library and
+ *	incorporated into Postgres for those systems which do not have this
+ *	routine in their standard C libraries.
+ *
+ *	The function was been extracted whole from the file inet_aton.c in
+ *	Release 5.3.12 of the Linux C library, which is derived from the
+ *	GNU C library, by Bryan Henderson in October 1996.  The copyright
+ *	notice from that file is below.
