== Additional information about MinGW and Windows Vista ==
In order to get MinGW properly working under Windows Vista, you need to do the following:
Go to Control Panel->System, and click on "Advanced System Settings" to the left. Then click on "Environment variables" and on the bottom window ("System variables"), select the "Path" variable and edit it. This variable tells windows where to look for binaries when it can't find them in the current folder. You'll find a lot of directories there separated by semicolons.
Make sure that the MinGW bin directory is included in the path (e.g. C:\MinGW\bin), which should already be included there from the MinGW installer. Also, make sure that the libexec path is included too (e.g. C:\MinGW\libexec\gcc\mingw32\3.4.2), which is needed in Vista to get MinGW properly working

From the developer's webpage: "MSYS or Minimal SYStem is a POSIX and Bourne shell environment use with MinGW. It provides a hand picked set of tools to allow a typical configuration script with Bourne syntax to execute. This allows most of the GNU packages to create a Makefile just from executing the typical configure script which can then be used to build the package using the native MinGW version of GCC".

It may be necessary to modify the bin/sdl-config and lib/pkgconfig/sdl.pc files  (located under the mingw directory) which are just text. These files provide the compiler option information to ScummmVM and SDL is passing the -mwindows compiler option by default which will result in a valid executable, but with broken console / command-line output. These should be removed or replaced by -mconsole (though this will affect all SDL compiled binaries made by the MinGW toolchain). ScummVM's configure script should deal automatically with this issue in future as the upstream SDL project has indicated that removing this "forced" option is a WONTFIX issue.
Note the README [http://www.libsdl.org/extras/win32/mingw32/README.txt here], especially the need to include the DirectX development headers from [http://www.libsdl.org/extras/win32/common/directx-devel.tar.gz here] to ensure that the "dsound" rather than the "waveout" / "winmm" fallback audio driver is used.
 
 
=== SDL2 ===
 
Note that a prebuilt version of SDL2 is required since MinGW32 doesn't have all the necessary Windows SDK headers.
