-**
-** Here be declarations of routines and variables in the C library.
-** Including this file is the equivalent of including all of the following
-** headers, portably:
-**
-** #include <sys/types.h>
-** #include <stdarg.h>
-** #include <stdio.h>
-** #include <stdlib.h>
-** #include <stddef.h>
-** #include <stdint.h>
-** #include <string.h>
-** #include <unistd.h>
-**
-** Missing functions are provided via #define or prototyped if we'll be
-** adding them to INN's library. If the system doesn't define a SUN_LEN
-** macro, one will be provided. Also provides some standard #defines.
