Well I would really like to have a Mac OS cross building environment,
because the Mac builds for PokerTH are always such a pain...

But - as they are such a pain, so will be creating the cross comp
environment. I don't want to discourage you, but you have to consider
the following:

There are different SDKs available for 10.4, 10.5, 10.6, 10.7, and you
should not expect that e.g. 10.4 executables run on 10.7 - some libs
won't even build using the 10.4 SDK because it is so bad... Then there
are several combinations: PPC, x86, x86_64, and all along with the
different SDKs. PPC won't run on 10.7, and there are even problems
building x86 using 10.5 SDK and running on 10.7. I was so frustrated
with this that now I only support the last two versions (10.6 and
10.7) using x86_64, and this works quite OK.

So maybe it would be better to define the limits early on, i.e. which
versions are supported and which machine targets...

But, as I said, a cross building environment for Mac would be very welcome :-).
