CMake HEAD (in CVS) uses a much better policy to determine path names to
reduce the cases in which the long names are encountered.  It also has a
way to automatically replace long path names with short ones in a unique
manner.  Unfortunately the changes are too extensive to port to the 2.4
release branch.
