Exactly!  "You must provide it yourself" -- therefore, Werner can't just
add in a check for every header file used unless he also puts thought
and effort into what to put into the `#if header_file_x_missing' branch.
But originally, you were saying that it was so easy to add checks for
every header file why no just do it?  I'm saying above that there is no
point doing the check unless the code is also altered to cope with both
answers -- yes it's present versus no it isn't.
