c34806796a Apparently it's possible that MSVC will want to call a built-in function to 
bitshift an Sint64, but it can't find this function since we don't use the
 C runtime on Windows.

Division doesn't have this problem, though. Strange.

  Thanks, Suzuki Masahiro.

d0a80f6b53 Fixed bug #292 
I might be on crack here.

It looks like SDL_ConvertMono() in src/audio/SDL_audiocvt.c adds the left and
right channels of a stereo stream together, and clamps the new mono channel if
it would overflow.

Shouldn't it be dividing by 2 to average the two sample points instead of
clamping? Otherwise the mono sample point's volume doubles in the conversion.
This would also make the conversion faster, as it replaces two branches per
sample frame with a bitwise shift.

--ryan.
