}

from SDL/SDL_gfxPrimitives.c:

int aalineRGBA(SDL_Surface * dst, Sint16 x1, Sint16 y1, Sint16 x2, Sint16 y2, Uint8 r, Uint8 g, Uint8 b, Uint8 a)
{
return (aalineColorInt(dst, x1, y1, x2, y2, ((Uint32) r << 24) | ((Uint32) g << 16) | ((Uint32) b << 8) | (Uint32) a, 1));
}

int aalineColorInt(SDL_Surface * dst, Sint16 x1, Sint16 y1, Sint16 x2, Sint16 y2, Uint32 color, int draw_endpoint)
{
Sint32 xx0, yy0, xx1, yy1;
int result;
Uint32 intshift, erracc, erradj;
Uint32 erracctmp, wgt, wgtcompmask;
int dx, dy, tmp, xdir, y0p1, x0pxdir;
// large function... truncated
}

will try subbing aalineRGBA for lineRGBA and see what happens...
