45 on some systems, but not on others. What's worse, you can't tell
46 at compile-time which one it will be, since it really depends on
47 the sort of system providing the filesystem you're reading from,
48 not the system you are running on. Paul Eggert
49 <eggert@bi.twinsun.com> says this occurs when Emacs is running on a
50 SunOS 4.1.2 host, reading a directory that is remote-mounted from a
51 Solaris 2.1 host and is in a native Solaris 2.1 filesystem.
