-/* lstat works differently on Linux and Solaris systems.  POSIX (see
-   `pathname resolution' in the glossary) requires that programs like
-   `ls' take into consideration the fact that FILE has a trailing slash
-   when FILE is a symbolic link.  On Linux and Solaris 10 systems, the
-   lstat function already has the desired semantics (in treating
-   `lstat ("symlink/", sbuf)' just like `lstat ("symlink/.", sbuf)',
-   but on Solaris 9 and earlier it does not.
-
-   If FILE has a trailing slash and specifies a symbolic link,
-   then use stat() to get more info on the referent of FILE.
-   If the referent is a non-directory, then set errno to ENOTDIR
-   and return -1.  Otherwise, return stat's result.  */
