For this to work, the compiler package (cmp.fas) must be loaded,
otherwise you'll get an error about undefined 'c' (or 'cmp')
package. As 'compile-file' loads the compiler package automatically,
you usually don't have to do it yourself. However in this case,
as you want to tune some internal variables, you have to load it
manually.
