The configure script for CVS HEAD now supports a --enable-ld-version-script option to enable the test for versioned symbol capability and use it if it is available. This option is disabled by default until we decide exactly what we want to do.

Please let us know if the 3.9 branch of libtiff needs similar treatment in order to accomplish what Debian requires.

I just did a little investigation. I checked my old emails regarding libjpeg symbol versioning and I dumped symbols on a Linux system with libjpeg 6b and libjpeg 8 to see what was done.

Unfortunately, it will also be necessary to add symbol versioning to the 3.9 branch of libtiff and Debian would need to re-build and re-link all software depending on 3.[8-9].X (or which wants to remain so) with the 3.9.X version with the symbol versioning. All of the existing software linking against libtiff would need to be re-linked before libtiff 4.0 can be safely introduced.
