/* stat 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
stat function already has the desired semantics (in treating
`stat ("symlink/", sbuf)' just like `stat ("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. */
