Igor - for the future, FYI, it's better to send dvipdfmx reports to
dvipdfmx at tug.org.

    Glyph width of 'C' in cmssdc10.tfm is 606.936.
    It is 609 in cmssdc10.pfb (cmssdc10.afm).

Akira - thanks for looking it up. Evidently it is a bug in the font. I
guess every cmssdc10.pfb C has been misplaced since day one :(. I guess
I could ask AMS about the chance of an update. (My guess is: low.)

I wonder if there are other pfb/tfm mismatches. Can you easily check this?
Or I can, eventually.

(If it won't ever get fixed, I guess dvipdfmx could make a special case
and omit the warning. Warnings that can't get fixed are noise that get
in the way of real messages ...)

Thanks,
Karl
