Can I conclude that most recent libtiff equiped systems (e.g. systems deployed or updated during the last five years) will support tiff/zip?

You can't really conclude anything at all. Yesterday I fixed a bug in my software related to libtiff 3.6.1. People are still using these old versions. Some commercial OSs don't automatically update to the latest version with each major release because they operate on the "If it ain't broke ..." principle.

Currently it is necessary to use defines from tiffconf.h to determine the libtiff build options used. Unfortunately, this is completely the wrong way to handle the problem. Libtiff should support a query function whereby an application can test to see if a library supports a feature at run-time.
