Fixed bug #216

The attached files allow building the SDL library and tests with the Open
Watcom compiler for Windows:
- static library or DLL
- Debug or Release builds available
- uses register calling convention of Open Watcom
- wmake target to build the SDL test samples

Following is a table that shows what works and what doesn't, yet:
checkkeys       +
graywin         +
loopwave        +
testalpha       +
testbitmap      +
testdyngl       +
testerror       +
testfile        +
testgamma       +
testgl          +
testhread       +
testiconv       - (all failed)
testkeys        +
testlock        + (after removing calls to raise() from signal handler)
testoverlay     + (needs 'set SDL_VIDEODRIVER=directx')
testoverlay2    + (-"-)
testpalette     +
testplatform    +
testsem         +
testsprite      +
testtimer       +
testver         +
testvidinfo     +
testwin         - (fading doesn't seem right)
testwm          +
torturethread   +
testcdrom       +
testjoystick    not tested
threadwin       +

TODO:
- make stack calling convention work (has linking issues with dxguid.lib)
- perform testjoystick (I don't have a joystick)
- investigate fading in testwin
- merge with OS/2 port
- add DOS target
