There is/was a problem loading tiff files, if only libtiff-5 was present.
A solution was renaming libtiff-3 to libtiff-5.
I announced a patch to the file-tiff plug-ins, that uses the opening of tiff files directly without using file descriptors.
The problem is, that libtiff uses different routines, when compiled in a windows environment, and these routines
uses the windows file handle, not the posix file descriptor, which is completely different.
The announced patch worked, but not for unicode filenames.
I announced a new patch today, which load/saves tiff files with libtiff-5 and using unicode.
The plugins attached uses this patch.
