You can easily create a deeply nested directory whose absolute file name
is longer than MAXPATHLEN.  The MAXPATHLEN (a.k.a PATH_MAX) parameter only
limits the length of the file name that can be passed to system calls, but
has no connection to maximum length of an (absoulte) file name in a system
(you can create virtually infinite long file names on Linux, for example).
