You're thinking of pointers in the ever popular 31-bit addressing
mode, where the high order bit isn't significant.  No such games with
ints, which don't vary in size between 31-bit addressing mode and
64-bit addressing mode:

/usr/include/limits.h:  #define INT_MAX       2147483647
/usr/include/limits.h:  #define UINT_MAX      4294967295U

--/--

Perhaps it was lost a couple of posts ago, but Joe's INT_MAX usage is
inside a Linux block and is needed only for a Linux "nuance".
