 * NET_SIZE_T exists because of shortsightedness on the POSIX committee.  BSD
 * systems used "int *" as the parameter to accept(), getsockname(),
 * getpeername() et al.  Consequently many unixes took an int * for that
 * parameter.  The POSIX committee decided that "int" was just too generic and
 * had to be replaced with size_t almost everywhere.  There's no problem with
 * that when you're passing by value.  But when you're passing by reference
 * this creates a gross source incompatibility with existing programs.  On
 * 32-bit architectures it creates only a warning.  On 64-bit architectures it
 * creates broken code -- because "int *" is a pointer to a 64-bit quantity and
 * "size_t *" is frequently a pointer to a 32-bit quantity.
 *
 * Some Unixes adopted "size_t *" for the sake of POSIX compliance.  Others
 * ignored it because it was such a broken interface.  Chaos ensued.  POSIX
 * finally woke up and decided that it was wrong and created a new type
 * socklen_t.  The only useful value for socklen_t is int, and that's how
 * everyone who has a clue implements it.  It is almost always the case that
 * NET_SIZE_T should be defined to be an int, unless the system being compiled
