I'll take a look.

That doesn't seem all that important.

Fine by me.

Ok too.

Ehh... if understand these are just the settings that you can override
on the command line for makefile.vc/gcc/whatever right? I would like
to try to get the OSX (xCode) build working and I even have an older
Mac to do it, but I haven't gotten around to it.

Hopefully, I also have visions of making the freeze program a little
better, like the python one that automatically pulls in all the
required libs, but there's absolutely no promises about that. I'm
thinking that overriding "require" to look into an attached wxTar/Zip
filesystem to an executable may work.

No... more for the compilation. For example, if a user downloads
wxWidgets and builds only some of the libs, leaving out media and gl,
they'll get linker errors. I don't think you can make linking in the
dsp files conditional on what wxWidgets libs you actually have?

Oh, that would be nice. I also want to make sure that only the minimum
wxWidgets libs are linked to each wxLua binding so that we'd get
linker errors if I happen to put anything from core into base, for
example.
=============
The separation is going to take a little longer than I thought, so let
me try to make some minimal changes to the bakefiles to get things
working again. I'll probably just cut & paste :) but I've already
added the AUI lib and there wasn't a lot that had to be added since
there's already quite a few shortcuts.
Thanks,
