39 /* The d_nameln member of a struct dirent includes the '\0' character
40 on some systems, but not on others. What's worse, you can't tell
41 at compile-time which one it will be, since it really depends on
42 the sort of system providing the filesystem you're reading from,
43 not the system you are running on. Paul Eggert
44 <eggert@bi.twinsun.com> says this occurs when Emacs is running on a
45 SunOS 4.1.2 host, reading a directory that is remote-mounted from a
46 Solaris 2.1 host and is in a native Solaris 2.1 filesystem.
