But ssize_t isn't int on all architectures... it's a long on
NetBSD/alpha, for example.

yerfable /usr/include/alpha> grep _BSD_SSIZE_T ansi.h
#define _BSD_SSIZE_T_           long            /* byte count or error */

yerfable /usr/include/alpha> grep 'SSIZE_MAX\|  LONG_MAX' limits.h
#define LONG_MAX        0x7fffffffffffffffL     /* max for a long */
#define SSIZE_MAX       LONG_MAX        /* max value for a ssize_t */
