-/* 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. */
