Since most good Ada compilers will do dead code elimination, an idiom
for small include/exclude sections is:
Debug_Version : constant boolean := True;
...
if Debug_Version then ... -- stuff_for_debug_version
else ... -- stuff_for_alternate_version
end if;
Since the truth/falsity of the constant Debug_Version is known
at compile time and can't change, the compiler can include the
desired code and eliminate the undesired.
You could make a configuration package with no body and a spec
consisting just of Debug_Version-like constant declarations if that
was appropriate.
