[metapost] Tfm generation broken

[Paul Pichaureau]

Hi,

I'm the developper of the mathdesign fonts. All of the outlines of these
fonts are produced from metapost sources (and then "packaged" as a font by
a python script).

Right now, I'm completly stuck. I cannot improve the fonts, and some
important bugs on mathdesign are yet to be solved.

To cut a long story short, I really need that this bug is solved on my
system. Do you think it could be possible to do a release of metapost in a
short delay ?

Of course, it"s not so urgent. I just want to be sure that it will be done
soon.

Thank you very much!
