Message 64836 - Python tracker

Humm, just saw the MSDN page Marc-Andre referred to, which indeed seems 
to indicate the Express edition doesn't support x64 cross-compilation 
*at all*.  AFAICT the latest Platform SDK (6.1) ships with an x64 cross 
compilation environment, but it's command line only, so unless there's 
a way to hook it up such that 'vcbuild' uses it with the Express 
edition as well -- it seems like you do need Standard edition or higher 
for x64 builds.
