  dnl Many systems enable large inodes if you enable large offsets.
  AC_REQUIRE([AC_SYS_LARGEFILE])

  dnl Some Mac OS X variants won't access large inode numbers by default.
  dnl Defining _DARWIN_USE_64_BIT_INODE fixes this.  See
  dnl <http://developer.apple.com/library/mac/releasenotes/Darwin/SymbolVariantsRelNotes>.
  dnl
  dnl The simplest thing is to define this symbol everywhere.
  dnl That helps on the affected systems, and doesn't hurt anywhere.
