Joris, I don't see any compelling reason libtiff could not be made to support bigtiff files smaller than 4GB on machines without a 64bit integer type. I would forsee the toff_t (and possibly tsize_t) types being 64 bits on platforms that allow it and 32bit otherwise. The code that reads the tags would need a special case for non-64bit-int platforms to downcast the values and throw some sort of error if there are any values that don't fit in a 32bit value. While I imagine it will be some time till BigTIFF support catches on for general use, I would not want to preclude it's use in all environments.
