Do you it's wise to use a combination of TIFFLIB_VERSION (which is monotonic *within* each branch, but not unique when comparing branches) and also detecting the presence of symbol TIFF_VERSION_CLASSIC, which should (I think) only exist in 4.x?

Probably not wise, but it seems like it will work today.
