Part of the offer was:

| Potentially we can even figure out how to enable anyone to | build Python using the freely downloadable compilers I mentioned | above...

Which is good news (don't get me wrong, I'm glad to see Microsoft supporting open source projects in this way). But wouldn't that imply unoptimised builds?

I just checked:

cl /O2 Microsoft (R) 32-bit C/C++ Standard Compiler Version 13.00.9466 for = 80x86 Copyright (C) Microsoft Corporation 1984-2001. All rights reserved.

cl : Command line warning D4029 : optimization is not available in the standard edition compiler

So, specifically, if PythonLabs releases Python 2.3 built with MSVC7, and I want to build the latest version of PIL, (maybe because Fredrik hasn't released a binary version yet), do I have no way of getting an optimised build (I pick PIL deliberately, because I guess that image processing would benefit from optimisation, and in the past, PIL = binaries have been relatively hard to obtain at times)?

That's the problem I see, personally. I have VC6 because my employer = uses Visual Studio for Visual Basic development. But VB has changed so much = in the transition to .NET, that I don't believe they will ever going to = VS7. So I will have to remain with VS6 (I'm never going to buy VS7 myself, = just for this sort of job).

Paul.
