Disable mouse acceleration

Has there been any progress with having a universal way to disable the
system’s mouse acceleration? control in my game seems to work pretty
well, but just a little acceleration makes it feel really squirrely.
Having SDL_GetRelativeMouseStateMouse() produce unmodified mouse
values would be great.

All I have found on this subject is a couple posts about
SDL_VIDEO_X11_MOUSEACCEL, but it isn’t universal and it isn’t working
for me with SDL 1.2.13.9. Maybe I need a newer version.–
