Hi Karl, hi all,
together with Frank we have developped a patch for fmtutil that deals
with the following problem:
On So, 07 Jun 2009, Frank Küster wrote:

The idea is that *if* a fmt file was generated and the string
'! '
(without ') are found at the beginning of a line then this was only a
*warning* and no error.
Currently fmtutil does in this case:
log_failure "pdftex -ini ... possibly failed."
and log_failure triggers and return value of > 0, which turns out as
error.
We have changed fmtutil by adding a new logging facility
log_warning
(all paralleling log_failure) that is used instead. Messages generated
from this will not change the exit value, but will be reported at the
end.
I attach the patch against current TeX Live's fmtutil in
Build/source/texk/tetex/fmtutil.
Please comment, esp. if you (I am having my Debian hat on) will accept
that patch into the upstream source.
Thanks a lot
Norbert
