I Filed two bugs in bugzilla regarding SDL and SDL_mixer when -Wundef and
-Wstrict-prototypes flags are one.The bugs and the attached patches can be
seen at:

Recently, I am writting a game based SDL-1.3, then found it is necessary
that modify some source code of SDL library. These code exist in both
SDL.dll and SDL_mixer.dll. I list here and hope to be good for SDL
developer.

SDL.dll, version: (SDL-1.3.0-5538)****************************************************
/audio/SDL_audiotypecvt.c
function: SDL_Upsample_S16LSB_2c_x2
Sint16 *dst = ((Sint16 *) (cvt->buf + dstsize)) - 2;
const Sint16 *target = ((const Sint16 *) cvt->buf) - 2;
===>update to
Sint16 *dst = ((Sint16 *) (cvt->buf + dstsize)) - 4;
const Sint16 *target = ((const Sint16 *) cvt->buf) - 4;

function: SDL_Upsample_S16LSB_2c
const int dstsize = (int) (((double)cvt->len_cvt) * cvt->rate_incr);
===>update to
const int dstsize = ((int) (((double)cvt->len_cvt) * cvt->rate_incr)) & ~3;

function: SDL_Downsample_S16LSB_2c
const int dstsize = (int) (((double)cvt->len_cvt) * cvt->rate_incr);
===>update to
const int dstsize = ((int) (((double)cvt->len_cvt) * cvt->rate_incr)) & ~3;

SDL_mixer.dll, version: (SDL_mixer-1.2.11)

<SDL_mixer-1.2.11>/load_aiff.c
function: Mix_LoadAIFF_RW
*audio_buf = malloc(*audio_len);
===>update to
*audio_buf = SDL_malloc(*audio_len);

<SDL_mixer-1.2.11>/load_ogg.c
function: Mix_LoadOGG_RW
*audio_buf = malloc(*audio_len);
===>update to
*audio_buf = SDL_malloc(*audio_len);
