When I run 
sh MAKEDEV all
using MAKEDEV from Sept 14/15, but sh from Sept 1, I get the following
message:

MAKEDEV: arith: syntax error:
"^H\xe0\x85^N^H^\\x86^N^H\xc8\x85^N^H\xe0\x85^N^H\
xe9\x85^N^H\xeb\x85^N^H\xee\x85^N^H^\\x86^N^H"

bad node: mknod i4bteld1

This seems like a strange error - if I make some randomish changes to
MAKEDEV I get some rather different responses - for example:

diff -u MAKEDEV-orig MAKEDEV
--- MAKEDEV-orig        Sat Sep 15 11:17:54 2001
+++ MAKEDEV     Sat Sep 15 11:18:25 2001

gives

gives no errors at all.

I am totally mystified - is it a bug in sh or something?
