{ Introduced defines
|
|
- 64bitarch (for 64-bits Linux systems, test system was idefix (in ctypes)
|
|
- 64bitfs (should be on if libc switches to a 64-bit system.
|
|
|
|
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
