I'm sorry, i must be dense, i'm still not getting this (i do not know
anything about the ICU board) ...

So, leave in the ifdef ICU862 case, but what about FADS (and other
boards) which may or may not have ENV_IS_EMBEDDED set?

shouldn't they also NOT initialize past the bss into environment.o if
ENV_IS_EMBEDDED is not set, but not refer to the "environment" symbol if


#if !defined(ENV_IS_EMBEDDED) || defined(CONFIG_ICU862)

Sorry that this is taking so long to explain, but now i'm hopelessly
confused ;/
