     `ifdef is subtly different. With a `ifdef the code is treated by the
     pre-processor and never even seen by the lexer as if it didn't exist.
     With `translate_on/off, it can be treated as if it exists and stored
     specially so that a single compile can be used for both simulation and
     synthesis.
     
     A better name would be appropriate if the committee so decided.
     Transalate_on/off were suggested because of the existing wied-spread
     use.
