I would suggest creating a subcase inside HAVE_OSX_XATTRS instead of a
completely separate case because both 10.3 and 10.4+ need the creation
time exposure code that is currently in osx-create-time.diff .

For now, I suggest that you focus on the creation time, the resource
fork, and the finder info; those seem to be the major things people care
about that rsync doesn't already preserve other ways.  For now, let's do
it the dumb way and use a separate getattrlist call for each.  In the
future, for improved performance, we could look into using a single
getattrlist per file to get both the stat data and all the Mac-specific
stuff at once, or even getdirentriesattr to get names and attributes for
everything in a directory at once.
