In this particular simple (and common) case, how about translating

> typedef struct {
>   int ncolors;
>   SDL_Color colors[]; // Actually is SDL_Color *colors but this is how
> it is laid out in memory
> } SDL_Palette;

to

type SDL_Palette(ncolors : interfaces.c.int) is record
  colors : SDL_Color_Array(1 .. ncolors);
end record;
for SDL_Palette use record
  ncolors at 0 range 0 .. 31;
end record;

I don't understand the following comment.  "colors" here is actually
an array, not a pointer, right?
