Nah, I think it's fine the way it is.  What's wrong with the "../" type
things in the include directives?  The build system works well with it,
you can build any single module or file correctly, and it's obvious what
the code is including from.

Now you might argue that the lustre code shouldn't have such a mess of
include files like this, and I would totally agree.  I suggest working
on reducing the number of .h files they have, and centralizing them such
that all of these cross-directory includes aren't needed anymore either
in the build directives, or in the .c files.
