Yeah, I do not have a good suggestion on the mechanism to actually
switch between behaviours other than what was already been discussed
in the thread, but the code resulting from the patch proposed is too
ugly with full of #ifdef for it to be the final form.
Just to make sure nobody gets me wrong; it is OK as a POC to move
the discussion forward.
A production quality implemention however would need to either be a
single executable that switches behaviour at runtime, or two
executables, each with its own *.c file with its own main(), that
share code in another common *.c file, I would think.
