Hmm.  Is this change necessary?

Yes, otherwise:

builtin-pack-objects.c: In function `prepare_pack':
builtin-pack-objects.c:1760: warning: passing arg 2 of `find_deltas' from incompatible pointer type
make: *** [builtin-pack-objects.o] Error 1

Note that ll_find_deltas() is #defined to find_deltas() in the #else arm
of #ifdef THREADED_DELTA_SEARCH, and find_deltas() takes an "unsigned *"

Ah, I missed that.  So it is not just warning squelch but is a bugfix in
case unsigned and uint32_t are of different sizes.
