I built it on IRIX 6.4, and I didn't get an error.
Anyway, as far as I can understand the code, to see if it is actually
a bug, type the following key sequence (make sure that is a capital Y):
    C-x 5 Y
You should get the following error (capital y):
    C-x 5 Y not defined.
If you get this one instead (lowercase y), then it's a bug:
    C-x 5 y not defined.
