- fs32bit, should be on if libc only supports sizeof(off_t)=4
we assume one typically compiles C applications with
#define _FILE_OFFSET_BITS 64
All three tested systems (PPC,Alpha,2x i386) gave the same POSIX limits,
and all three 32-bit systems returned completely identical types too
(everything 32-bit except dev_t, which is assumed to be a result of devfs
