-/* src/port/inet_aton.c
- *
- * 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.
