Fortunately... The clean (and compatible) way remains
hardware-specific units when needed and, within an unit,
constants keys like that:

with text_io; use text_io;

procedure condcomp is
 debug:   boolean:= false;
 verbose: boolean:= true;
 begin
  if debug then put_line("this is for debug"); end if;
  if verbose then put_line("verbosity"); end if;
 end;

Question: which compiler/optimizer will skip the unused
'put_line("this is for debug");' ?...
