[SDL] Windows Platform issues

SDL used Direct3D on windows by default.
I also ran into some problems when I tried to compile SDL as a static 
library. I ended up deciding to use SDL as a dll.
It would be nice if you could submit bugs to bugzilla, so your problems 
get documented and eventually get looked at.
