It doesn't really take an integer though. It takes a struct (not a pointer to
a struct) composed of four unsigned integers:
typedef struct SDL_Color {
Uint8 r;
Uint8 g;
Uint8 b;
Uint8 unused;
} SDL_Color;
SDL_Surface * SDLCALL TTF_RenderText_Solid(TTF_Font *font,
const char *text, SDL_Color fg);
Passing a pointer is definitely wrong, but it looks to me like we should
review the shifts of the individual components of the integer. That makes me
wonder if there's an endianness problem somewhere.

Can you send these as unified diffs next time? They're difficult to apply
this way.
