 *		- the maxumum name length for any file system type, or
 *		- should be _POSIX_NAME_MAX which is the minimum-maximum name
 *		  length in a POSIX conformant system (which just happens to
 *		  be 14), or
 *		- should be gotten by pathconf() or fpathconf().
 * XXX- I leave this to the owners of yp!
