00051  * Version: 1.0
00052  *
00053  * Date: 23 Sep 1996 - Original version.
00054  *
00055  * Version 1.1 8th June 1998
00056  *
00057  * Update referenced URL to be  http://www.opengroup.org/
00058  * and other changes to cope with UNIX 98
00059  * This program should now be compiled with the -DCKVERS_UNIX98
00060  * switch when checking for UNIX 98
00061  *
00062  * Version 2.0 16th Sept 2002
00063  *
00064  * Updated by Marc Rochkind (rochkind@basepath.com) to include
00065  * the Single UNIX Specification Version 3 (SUSv3).
00066  * This program should be compiled with -DCKVERS_SUSV3 to
00067  * enable checking for SUSV3. (Note: Some systems capable
00068  * of Unix98 support (_XOPEN_VERSION == 500) when _XOPEN_SOURCE is
00069  * set to 500 revert to _XOPEN_VERSION == 4 if _XOPEN_SOURCE is
00070  * set to 600. So, if you don't get 600 when you set -DCKVERS_SUSV3,
00071  * you should go ahead and try -DCKVERS_UNIX98 as well.
00072  *
00073  * At the time of writing the brand name for the UNIX mark for
00074  * the Single UNIX Specification Version 3 is yet to be finalized.
