[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [45561] trunk/blender/source/blender/ blenkernel/BKE_global.h: add in a check for Mingw so 4. 5 or older will error out on build.

[Sergey Sharybin]

I didn't experience any issues with libmv in my setup, only cycles gave
errors.
Ofcourse i can use another mingw to compile blender, but it's kind of crap
which i think might be avoided :S
