[Pythonmac-SIG] 64-bit Python?

[Boyd Waters]

Interesting! Cool!

I should look at the header file in the System Python...

I had to patch the Python.h in the standard Python distribution to have
the "ifdef 64-bit" conditional code, so that the single header file works
with both 32- and 64-bit.

NOTE that the patches I used in the modified MacPorts came from Apple:
