Re: [Boost-users] [config] disabling _MSC_EXTENSIONS disables win32

The point is that with /Za you can't #include windows.h or use any platform specific features, so that makes it very hard (impossible?) to compile code that is binary compatible between /Za and not /Za.

Ok, I see now, I jumped to conclusions too quickly... So it turns out that /Za is absolutely useless for any win-based development, which is very frustrating.
