Consider adopting the clever hack mentioned recently in another
newsgroup.  Under UNIX if the link count for a directory is 2 or less,
it has no subdirectories and you need not perform the stat(2) on each of
its files.  If it has link count 3 or greater, subdirectories exist, but
you need only keep stat(2)'ing until you have found (link count - 2) of
them, after that everything must be a file.

This is admittedly UNIX dependent but would be worth having optionally
in config.h for those who want it.
