to get the new unsetenv behaviour on Tiger, you need to have this defined:

__DARWIN_UNIX03

by patch, flag, hack, compiler wrap, hook-or-by-crook, however you get it defined.

(The build seem to be hiding the build lines still, so you have no idea what is defined and what is not defined just now -- you have to disable silent rules, increase the verbosity, etc, etc ,etc to see what you are sending the compiler).

Aside -- the SDK headers on Tiger are quite a bit different from Leopard+, and LOTS of things are headaches on Tiger that are not headaches on Leopard+, like @rpath handling, etc, etc, etc.

So Tiger is a mess/labour of love that you have be pretty invested in to bother fixing all the issues that come up.

Got it. I am not planning to spend much effort on Tiger, tbh: I rather do more for 10.5/10.6. I thought it would be nice to have a number of basic R packages working, but it is not something that I gonna ever use personally.

16. S. On a side note, why it enjoys that much of following, when nothing works?

TIger runs on all the really really old PowerPC systems (G3, etc) which gets some machines running that can't run Leopard -- and it runs MacOS9 in a very functional "Rosetta" emulator layer that works really quite well, so it opens the door to all the ancient stuff (and I have tons and tons and tons of ancient stuff from that era, for example). I have a couple of systems set up for Tiger.
