In rdiff-backup, librsync doesn't actually do any file handling.  Data
is supplied to and read from librsync with python routines.  So the
issue probably is not whether librsync was compiled with large file
support, although there might still be some limiting constant in there
somewhere.

I'm using python v2.2.1 that came with redhat 8.0 I think.  librsync I
compiled my own from the old 0.9.5.1 package.  However, the version of
librsync in CVS is much newer and supposedly better, so you may want
to try that.  (In fact, I just upgraded now.  NB: Assuming you are
using a shared library librsync now, remember to ./configure
--enable-shared when you use the CVS version.)

You may also want to try using 'rdiff' directly, to just make a
signature of a large file, try producing a delta of two large files,
and/or patching a large file with a large delta.
