00050  *  26-Feb-97 - Original Version, extracted from config.c.
00051  *
00052  * Description:
00053  *
00054  * Configure the -TARG group (included in config.c).
00055  * See config_targ_opt.h for usage conventions.
00056  * See config_targ.* for more general target configuration support.
00057  *
00058  * NOTE:  There is an approximate distinction between -TARG option
00059  * group flags and their configuration (in this file), and more generic
00060  * target configuration (in config_targ.c).  Note that the related
00061  * header file config_targ.h is included in config.h, and hence in most
00062  * source files, whereas config_targ_opt.h is only included directly, so
00063  * putting new -TARG option-related variables in here is to be
00064  * preferred to putting them in config_targ.[hc].
