[Python-Dev] Issue 22919: Update PCBuild for VS 2015

[Steve Dower]

FYI, I've just committed these changes (http://bugs.python.org/issue22919).

There shouldn't be any immediate failures, as the updated projects will still build with VS 2010, but our Windows developers/buildbots can migrate onto the later tools as they feel comfortable.

I know there are at least a few bugs coming out of the new compiler, so I'll be tracking those down and fixing things. Feel free to nosy me (or Windows) on the issue tracker if you find anything.

Cheers,
Steve
