00053  * Revision history:
00054  *  05-May-96 - Extracted from be/opt/opt_config.h.
00055  *
00056  * Description:
00057  *
00058  * Declare global flag variables for -OPT group options.
00059  * This file is included in common/com/config.c.
00060  *
00061  * Declarations of -OPT flags should be put here, instead of in
00062  * config.h.  The intent is to allow updates of the -OPT group
00063  * without forcing recompilation of everything that includes config.h.
00064  * (However, the transfer of the flags' definitions here from config.h
00065  * is not yet complete, so most of the old ones still require
00066  * config.h.)
00067  *
00068  * ====================================================================
00069  * WARNING: WHENEVER A NEW FLAG IS ADDED:
00070  * ###  - Add the flag variable declaration to config_opt.h (here) .
00071  * ###  - Add the flag variable definition to config_opt.cxx .
00072  * ###  - Add the option to the group description in config_opt.cxx .
