-* $Log: Getopt.c,v $

-* Revision 1.4  2005/05/04 17:54:00  mridge

-* Update to version 1.2.8

-*

-* Revision 1.4  2002/03/30 01:32:14  yardleyb

-* Major Changes:

-*

-* Added Dumping routines for

-* data miscompares,

-*

-* Updated performance output

-* based on command line.  Gave

-* one decimal in MB/s output.

-*

-* Rewrote -pL IO routine to show

-* correct stats.  Now show pass count

-* when using -C.

-*

-* Minor Changes:

-*

-* Code cleanup to remove the plethera

-* if #ifdef for windows/unix functional

-* differences.

-*

-* Revision 1.3  2002/02/21 21:32:19  yardleyb

-* Added more unix compatability

-* ifdef'd function out when

-* compiling for unix env. that

-* have getopt

-*

-* Revision 1.2  2002/02/04 20:35:38  yardleyb

-* Changed max. number of threads to 64k.

-* Check for max threads in parsing.

-* Fixed windows getopt to return correctly

-* when a bad option is given.

-* Update time output to be in the format:

-*   YEAR/MONTH/DAY-HOUR:MIN:SEC

-* instead of epoch time.

-*

-* Revision 1.1  2001/12/04 18:57:36  yardleyb

-* This source add for windows compatability only.
