I am not replacing the following header files used by the Windows build, as I don't have a Windows build setup to test. Please point the Windows build at the header files inside these clean distribution packages and garbage collect the duplicates: GLew/*.h and SDL/Include_1.2. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5711 8ced0084-cf51-0410-be5f-012b33b47a6e
