43 /* The d_nameln member of a struct dirent includes the '\0' character
44 on some systems, but not on others. What's worse, you can't tell
45 at compile-time which one it will be, since it really depends on
46 the sort of system providing the filesystem you're reading from,
47 not the system you are running on. Paul Eggert
48 <eggert@bi.twinsun.com> says this occurs when Emacs is running on a
49 SunOS 4.1.2 host, reading a directory that is remote-mounted from a
50 Solaris 2.1 host and is in a native Solaris 2.1 filesystem.
51
52 (and Solaris 2 doesn't have a d_nameln member at all! Posix.1
53 doesn't specify it -- mrb)
54
55 Since applying strlen to the name always works, we'll just do that. */
