However, if you use the Kernel Library, you probably do not want the
objects in /kernel to include your special file. As discussed on this
list recently, use the path_special() hook outlined in
/doc/kernel/hook/driver instead:

  1. Create the empty file: /include/AUTO
  2. Add this line to /include/std.h: # include "AUTO"
  3. From ~System/initd, register an object manager in the driver.
  4. Let path_special() in the object manager return the path of the
     file to include.

I found this a bit tricky the first time, because it took me a while
to figure out that I had to create the empty file as described in
step 1 above. This file will actually be included by objects in
/kernel and ~System, that is why it should be empty.
