[Bf-committers] Windows XP and the future of Blender

[Jürgen Herrmann]

MinGW 64 breaks OpenMP in win 8 too.
There is no problem supporting Windows XP with VS2012 anymore.
We'll just have to keep in mind using the right platform toolset.
An we have to keep in mind that some features won't work.

So I would suggest we compile the 32bit blender binaries with vs 2012 and the v110_xp toolset and just drop xp64 support by compiling blender with default v110 toolset for x64 windows.

So we don't have to maintain two windows build platforms, just one.
Makes it easier to stay up to date with libs.
