mknod bug? major minor's are whacky

[Bob Goldberg]

cygwin 1.7.6

attempting to:
$ mknod null c 1 3

what I get is:
crw-rw-rw- 1 user mkgroup-l-d 46200, 14467 2010-08-17 18:44 null

WHERE did those crazy major/minor's come from!?!?

and how do I re-create a null device if mknod doesn't work right?
TIA
