What I really don't understand is that I get this overflow at all!
Why is an `:=' assignment handled as an `independent variable' (in
MetaFont parlance), especially if all elements on the right side are
non-variant data elements only? I looked up the MetaFont source, but
it is too confusing for me... Or is something different the cause?
I haven't had yet contacted a MetaFont mailing list (assuming that
most experts are reading both lists).
BTW, the warning comes from an addition in `mf.ch', which adds a check
for overflow of the serial numbers.
