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

[Jürgen Herrmann]

Another problem with these MinGW libs is that they can cause crashes on Windows 8 x64 systems when linked to binaries built with MSVc2012.
Because they seem to use an old MSVCRT that causes some trouble.
That's why I try to build everything with native MSVC compilers. I even found a way to recompile Jack with vc11.
