off_t is 64-bit on FreeBSD in both i386 and x86-64 modes.

This comment is mildly confusing with the addition of FreeBSD to the #if. FreeBSD is "special" in the same way that Mac and Linux/x86-64 are.
The warning above clearly explains the issue. Probably just remove the "Mac and..." comment as it's redundant with the test.
