Compilation is tested in every incremental patch.

This file provides lower level functions used only by code in 08, hence

it is added to the Makefile at 08.

For the next iteration, I'll decouple 07 and 08, but I think it makes 
sense to

keep the Makefile changes at 08 when the functionality is actually added

to the driver.

Agree. Using the constants directly will also help to decouple 07 and 08.
