[NTG-context] beta: warning messages

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} - Peter
