Hi Hans,
looks my knowledge of TeX is holey like a Leerdammer. Can you tell me
why you fire a warning for already defined, non-global allocated registers?
Some of them make sense here but even a grouped (and local allocated)
register gives such a warning.
warning : \count \OLDpdfcompresslevel is already defined (\relax
it first)
\def\disablePDFcompression%
{\bgroup
% \let\OLDpdfcompresslevel\relax
\newcount\OLDpdfcompresslevel
\OLDpdfcompresslevel\pdfcompresslevel
\pdfcompresslevel\zerocount\relax}
\def\allowPDFcompression%
{\pdfcompresslevel\OLDpdfcompresslevel\egroup}

Because it's nonsense what you do, just assign the value to your
counter inside of the group and will be keeped local.
\newcount\OLDpdfcompresslevel
\def\disablePDFcompression
{\bgroup
\OLDpdfcompresslevel\pdfcompresslevel
\pdfcompresslevel\zerocount\relax}
\def\allowPDFcompression
{\pdfcompresslevel\OLDpdfcompresslevel\egroup}

first of all, there is a command \nopdfcompression so you don't need the
hackery
then, \newcount is global and the latest releases of context catch
redefinitions so:
- either move the \newcount outside the macro
- or relax it first (which will spoil a counter then)
(the whole allocator has been rewritten and is no longer doing it in the
traditional tex way, at least not with respect to where things end up;
cleaner this way)

actually, i could probably make a global as well as a local registre
pool (thr trick is in avoiding stack buildup)

there are:
\def\nopdfcompression {\pdfobjcompresslevel\zerocount
\pdfcompresslevel\zerocount}
\def\maximumpdfcompression{\pdfobjcompresslevel\plusone
\pdfcompresslevel\plusnine }
\def\normalpdfcompression {\pdfobjcompresslevel\plusone
\pdfcompresslevel\plusthree}
with
\normalpdfcompression
being default

well, the code is messed up this way, because i had also disabled
\pdfobjcompresslevel in a prior version.
after i found out, that you can't change it at runtime (only once at the
very beginning of the document) i removed it. the rest of the macro was
unchanged.
