*Usage Note:* Don't use `FILENAME_MAX' as the size of an array in
which to store a file name! You can't possibly make an array
that big! Use dynamic allocation (*note Memory Allocation::)
instead.
Also, there is not guaranteed to be an actual limit to path strings -
and some library calls which return paths may return strings lonter
than FILENAME_MAX, I believe. In the event that there is no actual
limit, PATH_MAX is not guaranteed to be defined, and FILENAME_MAX will
be defined to a very large number.
