-/* Record the location of the current working directory in CWD so that
-   the program may change to other directories and later use restore_cwd
-   to return to the recorded location.  This function may allocate
-   space using malloc (via xgetcwd) or leave a file descriptor open;
-   use free_cwd to perform the necessary free or close.  Upon failure,
-   no memory is allocated, any locally opened file descriptors are
-   closed;  return non-zero -- in that case, free_cwd need not be
-   called, but doing so is ok.  Otherwise, return zero.
-
-   The `raison d'etre' for this interface is that the working directory
-   is sometimes inaccessible, and getcwd is not robust or as efficient.
-   So, we prefer to use the open/fchdir approach, but fall back on
-   getcwd if necessary.
-
-   Some systems lack fchdir altogether: e.g., OS/2, pre-2001 Cygwin,
-   SCO Xenix.  Also, SunOS 4 and Irix 5.3 provide the function, yet it
-   doesn't work for partitions on which auditing is enabled.  If
-   you're still using an obsolete system with these problems, please
-   send email to the maintainer of this code.  */
