Avoid EOVERFLOW from stat() calls due to overflowing inode numbers.
The btrfs filesystem now uses 64-bit inode numbers even on 32-bit systems.
This can lead to spurious stat() failures, where EOVERFLOW is returned because
the inode number does not fit into the 32-bit stat structure, even when the
caller is not interested in the inode number. This patch builds with
_FILE_OFFSET_BITS == 64 when possible, and deals with integers that may be
too large to fit into a Lisp fixnum. For more information, see xemacs-patches
