There are some discussion about these _LARGEFILE64_SOURCE usage on zlib
developers' mailing list.

To put it short, it's now believed that the usage of _LARGEFILE64_SOURCE
on FreeBSD is wrong.  I'm not quite sure though, if I should use some
workaround over this, like Mac OS X did (newer zlib has a similar change
by requiring _LFS64_SOURCE):
