The conditional compilation was some time a topic in the discussion on
how to build an Ada compiler. But this discussion has stopped. I would
prefer a conditional compilation (omitting code from conditional or
loop statements, which will never be executed e.g. if false then ... end if;)
to the #ifdef implementation with a preprocessor for two
reasons:

1. It would be just a change in the compilers IMPLEMENTATION

2. The settingsof constants used for conditional compilation
   can be verified later with the change control system.

kind regards
armin
