I did some work on top of your rsync10.3xattr_support080211 files.  I
added code to configure.in and Makefile.in that should get the
appropriate -I option passed for lib/sysxattrs.c in the case of
HAVE_PRE_TIGER_OSX_ATTRS.  You can modify the option in configure.in if
necessary.  I put * instead of 3.9 to try to make the option work on
pre-Tiger systems other than 10.3.9.

I also think I figured out why the configure script was refusing to
enable HAVE_PRE_TIGER_OSX_ATTRS.  First, every time you change
configure.in, you need to run "autoconf -o configure.sh" to update
configure.sh (the underlying configure script for which ./configure is a
simple wrapper).  The ./configure wrapper will invoke autoconf to
generate configure.sh if it doesn't exist, but once it exists, you have
to regenerate it yourself as necessary.  Second, the [] characters in
"darwin[4-7]*" in configure.in are recognized by autoconf as quoting
characters and stripped out, so configure.sh says "darwin4-7*" , which
obviously won't match.  I changed configure.in to say "darwin[[4-7]]*" ;
autoconf strips only the outer pair to leave the desired "darwin[4-7]*"
in configure.sh.

I also neatened up the code in other places and finished your strncpy
call.  A patch with my proposed changes on top of your files is
attached.
