Ok. Some hacking around and this is the output that I am getting on
my Xeon Workstation now. And also there is still some discussion on
what exactly is meant by "Is64Bits". Julien, can you comment on that?
This should be the number of bits of the OS, but I don't think it
has been fully tested, meaning that if you run a 32 bits OS on a 64
bits processor, it might return Is64Bits=1. We need to double check
that.
When you compile on OS X 10.5.7 32 bit do you get a fully functional
64-bits executable?

Not unless I specifically tell cmake to compile using X86_86 as the
arch.. Hang on..
I set the CMAKE_OSX_ARCHS to x86_64 and compiled and reran the test
program:

Is64Bits shows true which is correct. I was really asking if the
Is64Bits was referring to the CPU Capability or to the OS or to how
CMake was built. I can have any combination of the 3 on OS X.
