Is LIBTIFF 4.0.3 ABI compatible with libtiff 3.9.5?
libtiff4 is source-compatible but not binary-compatible with libtiff3. The breaks were necessary to support large files.
FWIW, my experience with updating the Fedora distro is that 4.0 is only about 99.9% source-compatible either. There were a few packages that required source-code fixes (freeimage, tkimg, xloadimage according to my notes). As an example, the library no longer exposes the contents of struct TIFFFieldInfo.
