Barbara and Karl,
you may have seen here that the problem turned out to be
a MiKTeX feature in the first instance. Incidentally, however,
it led me to a problem with mktexpk. I have just learnt from
the TeXpert at the computing center that the mktexpk I have
used is just from the current TeXLive distribution, so will you
be please care for the latter if there indeed is a bug?
Now I did:
mktexpk --dpi 600 --bdpi 600 --mag 0 --mfmode ljfour fibr84
The screen then was crowded with error messages,
it seems that division by 0 is tried some hundreds of times,
I am sending the .log containing 15 200 lines separately.
fibr84.tfm and fibr84.gf are announced, but fibr84.gf is _not_
mf '\mode=ljfour; mag=magstep(0);' input fibr84
works (I just tested the .pk with my 300dpi printer, and it
seems to be OK). So I think mf is OK, there is no bug to
be reported to Knuth, and I won't win anything from him
(as the METAFONT book somewhere announces).
Now, I have tried mktexpk on cmcsc10 at magsteps 2
and 5 like above, and both failed! Unfortunately, I cannot
get the .log's, and "more" didn't help, I only see that
there are no errors in processing the characters, yet the
output is cmcsc10.1200gf, e.g., a proof output, i.e.
The final message is that it failed indeed.
I cannot go on this way because the outcomes seem
to go to directories at the computing center to which
I don't have access -- well, I have another idea, but
now I must go shopping.
