This configuration times searching long lists of CPPPATH directories.
We create $DIR_COUNT on-disk directories. A single checked-in .h file
exists in the 'include' directory. The SConstruct sets CPPPATH to a
list of Dir Nodes for the created directories, followed by 'include'.
A checked-in .c file #includes the .h file to be found in the last
directory in the list.
