Hmm. The tif_open.c changelog says what has changed, but not *why* it has changed.

Even BigTIFF support doesn't imply any need for compile time endian dependent
(nor 64 bit dependent) code.

You could write BigTIFF support in such a way that it will run on a 32 bit
machine, and doesn't even need compiler support for long long. You may not
want to this of course.
