SDL is already compiled and needs no further changes, so we can skip the compilation step for it.
'''Note for x64''': You will need to compile SDL for x64 on your own (as of the time of this writing), to do so you will also need to install the [http://msdn.microsoft.com/en-us/directx/default.aspx DirectX SDK found here]. You will also need to apply
this patch [http: // robertmegone. com/ scummvm/ build/ sdl. patch from here] ( patch gladly taken from the SDL mailing list) .
After adding a new x64 configuration option in the project files, you may also need to remove "/MACHINE:I386" as additional linker command in Project->Properties, Configuration Properties->Linker->Command Line.
