Re: [Visualpython-users] AMD64 build error

[Bruce S. <Bru...@nc...>]

Thanks again for the patch. I simply changed int to long, checked that 
it works on a 32-bit Windows machine, and committed the change to CVS.

I'm a little surprised that a 64-bit machine environment didn't shake 
loose more than just this one problem.
