FWIW I have tested the basic idea back as far as OSX 10.6, and it works
fine there with the system gcc 4.2.1

so the `include_next` directive is fine that far back...
OSX 10.6 is the oldest I can test, but it would be interesting to see if
it also works on 10.5 (PPC)....

Hi,
I am interested in working on this, as I think it would ease some
issues in a few ports I have stumbled over recently. Let me try and
put something to test together.
I have started to put something together for this. I have a little new
project in github
https://github.com/cjones051073/macports-legacy-support
and then a new port that installs the headers from this repo.
<https://github.com/cjones051073/macports-ports/commit/f1b25a6dea9e895ae6d1d14411099b6cd43153ea>
I have run a first quick test, building xrootd, and the signs are
positive in that as I hoped it fixed the issues I was seeing with xrootd
completely transparently, without having to patch the port or code in
anyway. Obviously much more testing is needed though, so please if you
are interested (Ken?) checkout my ports branch above and give it a try
yourself.
Also, if you have any suggestions for additional header fixes to add,
let me know (or make a PR against the project...). ( Longer term, if
this idea has legs, I think the git repo should move from my account to
the main MacPorts area, but this can wait. )
