+Verify that use of a Scanner that searches a *PATH list doesn't create
+nodes for directories that don't exist, so they don't get picked up
+by DirScanner.
+
+Under the covers, this tests the behavior of the SCons.Node.FS.find_file()
+utility function that is used by the Scanner.Classic class to search
+directories in variables such as $CPPPATH.
