I am using Python 2.4. I need to make a native Python extension for
Windows XP. I have both VC++ 6.0 and Visual C++ 2005 Express Edition.
Will VC++ 6.0 do the trick? That would be easier for me, because the
project is written for that one. If not, will the 2005 compiler do it?
Thanks much,

Jeremy Martin, nowadays a parallelfor can be useful, and in future
I'll try to introduce similar things in D too, but syntax isn't
enough. You need a way to run things in parallel. But Python has the
