Re: [ANNOUNCEMENT] Updated: tiff-3.5.6beta-2

Hi all !

I have just tried to compose with  `pdflatex' (linked to `pdftex') and
now a window emerges with the following error message:

The PDFTEX.EXE fle is linked to missing export CYGTIFF3.DLL:TIFFOpen

Note that the DLL is still present in `/usr/bin':

Is it a bug ?

Thanks,
Jerome BENOIT
