[Mesa-dev] [PATCH] include, auxiliary: Remove support for MSVC older then 2008.

[Jose Fonseca]

MSVC 2008 (shipped with Windows SDK 7.0.7600) is the oldest we
need to support.  At least on llvmpipe, gallium/auxiliary, and util
modules.  For the remaining modules (particular all OpenGL specific
code) can be built with MSVC 2013.
