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
