Main SDL downloads...

Mixer downloads...

Ditto. SDL does build though. No DX headers or libs here either, just
DX3 as is installed by whichever service-pack. The build notes its
absence then continues. Nothing else to report atm, this was mainly to
let you know the links.

Oh, SDL 'configure' with no options for cygwin yields a mingw
automatically (and an sdl-config with -mno-cygwin within it).
