That would certainly be more logical.  In order to make that change,
you would have to consider each use of the macro to confirm that the
change would be valid.

As far as I can see, all but one use of this macro is in target
dependent code.  Are you having trouble from the single target
independent use?  Or perhaps your target dependent code should just
use REAL_VALUE_TO_TARGET_SINGLE instead?
