* Get (mostly) rid of CFG_MONITOR_LEN definition; compute real lengthLABEL_2003_05_30_1450
instead CFG_MONITOR_LEN is now only used to determine _at_compile_ _time_ (!) if the environment is embedded within the U-Boot image, or in a separate flash sector. * Cleanup CFG_DER #defines in config files (wd maintained only)
