This configuration is for testing the timing of searching long lists of
CPPPATH directories.

We create 100 on-disk directories, with a single .h file in the last
directory in the list.  We set CPPPATH to a list of Dir Nodes for the
created directories.  The .c file we create #includes the .h file to be
found in the last directory in the list.
