+Using SDL under Windows with the OpenWatcom compiler
+I have done the port under Windows XP Home with SP2 installed. Windows
+2000 should also be working. I'm not so sure about ancient Windows NT,
+since only DirectX 3 is available there. Building should be possible,
+but running the compiled applications will probalbly fail with
+SDL_VIDEODRIVER=directx. The windib driver should work, though.
+To compile and use the SDL with Open Watcom you will need the following:
+- Open Watcom compiler. I used version 1.5. The environment variables
+  PATH, WATCOM and INCLUDE need to be set appropriately - please consult
+  the OpenWatcom documentation and instructions given during the
+  installation of the compiler.
+  My setup looks like this in owvars.bat:
+    set WATCOM=C:\watcom
+    set INCLUDE=%WATCOM%\h;%WATCOM%\h\nt
+    set PATH=%PATH%;%WATCOM%\binnt;%WATCOM%\binw
+- A fairly recent DirectX SDK. The original unmodified DX8 SDK works, as
+  well as the minimal DirectX 7 SDK from the Allegro download site
+  (<>).
+- The SDL sources from Subversion
+- The file (now available in Subversion)
+Building the Library
+1) In the SDL base directory extract the archive This
+   creates a subdirectory named 'watcom'.
+2) The makefile expects the environment variable DXDIR to be set to the
+   base directory of a DirectX SDK. I have tried a stock DX8 SDK from
+   Microsoft as well as the minimal DirectX 7 SDK from the Allegro
+   download site.
+   You can also edit the makefile directly and hard code your path to
+   the SDK on your system.
+   I have this in my setup:
+     set DXDIR=D:\devel\DX8_SDK
+3) Enter the watcom directory and run
+     wmake sdl
+4) All tests from the test directory are working and can be built by
+   running
+     wmake tests
+ The makefile offers some options to tweak the way the library is built.
+ You have at your disposal the option to build a static (default)
+ library, or a DLL (with tgt=dll). You can also choose whether to build
+ a Release (default) or a Debug version (with build=debug) of the tests
+ and library. Please consult the usage comment at the top of the
+ makefile for usage instructions.
+ If you specify a test target (i.e. 'wmake tests' for all tests, or
+ selected targets like 'wmake testgl testvidinfo testoverlay2'), the
+ tests are always freshly compiled and linked. This is done to
+ minimise hassle when switching between library versions (static vs.
+ DLL), because they require subtly different options.
+ Also, the test executables are put directly into the test directory,
+ so they can find their data files. The clean target of the makefile
+ removes the test executables and the SDL.dll file from the test
+ directory.
+ To use the library in your own projects with Open Watcom, you can use
+ the way the tests are built as base of your own build environment.
+Test applications
+I've tried to make all tests work. The following table gives an overview
+of the current status.

+testwm          +
+torturethread   +
+testcdrom       +
+testjoystick    not tested
+threadwin       +
+There is room for further improvement:
+- Test joystick functionality.
+- Investigate fading issue in 'testwin' test.
+- Fix the UTF-8 support.
+- Adapt the makefile/object file list to support more target systems
+- Use "#pragma aux" syntax for the CPU info functions.
