* limits.h - POSIX compatible defnitions for some of <limits.h>

* DESCRIPTION
|
|
|
8 |
*
|
|
|
9 |
* We need to include <limits.h> if this system is being compiled with an
|
|
|
10 |
* ANSI standard C compiler, or if we are running on a POSIX confomrming
|
|
|
11 |
* system. If the manifest constant _POSIX_SOURCE is not defined when
|
|
|
12 |
* <limits.h> is included, then none of the POSIX constants are defined
|
|
|
13 |
* and we need to define them here. It's a bit wierd, but it works.
|
|
|
14 |
*
|
|
|
15 |
* These values where taken from the IEEE P1003.1 standard, draft 12.
|
|
|
16 |
* All of the values below are the MINIMUM values allowed by the standard.
|
|
|
17 |
* Not all values are used by the PAX program, but they are included for
|
|
|
18 |
* completeness, and for support of future enhancements. Please see
|
|
|
19 |
* section 2.9 of the draft standard for more information on the following
|
|
|
20 |
* constants.
