This allows regions that hold variable storage to be marked as data that is initialized by the program before it is used. Previously the choices were to treat it as bulk data (initialized) or junk (totally unused), neither of which are correct. This is functionally equivalent to "junk" as far as source code generation is concerned (though it doesn't have to be). For the code/data/junk counter, uninitialized data is counted as junk, because it technically does not need to be part of the binary.
