30 * Gallium configuration defines.
32 * This header file sets several defines based on the compiler, processor
33 * architecture, and operating system being used. These defines should be used
34 * throughout the code to facilitate porting to new platforms. It is likely that
35 * this file is auto-generated by an autoconf-like tool at some point, as some
36 * things cannot be determined by pre-defined environment alone.

60 * Meaning of _MSC_VER value:
61 * - 1800: Visual Studio 2013
62 * - 1700: Visual Studio 2012
63 * - 1600: Visual Studio 2010
64 * - 1500: Visual Studio 2008

66 * - 1310: Visual C++ .NET 2003
67 * - 1300: Visual C++ .NET 2002
69 * __MSC__ seems to be an old macro -- it is not pre-defined on recent MSVC
