SDL problem

Ok, this is my minimal testcase for a problem I'm having with SDL_CreateRGBSurface(), or something around that area...  It's supposed to display a white box but something is wrong with the mask values I give to SDL_CreateRGBSurface and the only color I can get is this dark red.  I know it has nothing to do with the palette values so don't even bother.  Can anyone who's familiar with SDL tell me how to fix this shit?

#include <assert.h>
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <SDL/SDL.h>

void setpalette(SDL_Surface* surface);

/*** Main Entry ***/
int WINAPI
WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nCmdShow) {

        SDL_Surface* screen;
        SDL_Event event;


        /* Start SDL */
        if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_TIMER) == -1) {
                printf("Failed to initialize a subsystem.\n");
                exit(1);
        }


        assert((screen = SDL_SetVideoMode(640, 480, 8, SDL_SWSURFACE)) != NULL);


        setpalette(screen);


        // Clear the screen
        SDL_FillRect(screen, NULL, 0);

        SDL_Surface *area;
        SDL_Rect rectarea = { 100, 100, 400, 400 };

        /*** FAIL TIEM ***/
        area = SDL_CreateRGBSurface(SDL_SWSURFACE, 111, 221, 8, 0x000000FF,0x0000FF00,0x00FF0000,0);

        assert(area != NULL);
        assert(!SDL_FillRect(area, NULL, 15));   // Color 15 should give me a white box
        SDL_BlitSurface(area, NULL, screen, &rectarea);

        SDL_Flip(screen);
        SDL_FreeSurface(area);


        while (1) {
                SDL_PollEvent(&event);

                if (event.key.type == SDL_KEYDOWN) {
                        // Escape: exit the program
                        if (event.key.keysym.sym == SDLK_ESCAPE)
                                break;
                }
        }

        SDL_Quit();
        return 0;
}


void setpalette(SDL_Surface* surface) {
        SDL_Color colors[256];
        colors[0].r = 0; colors[0].g = 0; colors[0].b = 0;
        colors[15].r = 255; colors[15].g = 255; colors[15].b = 255;
        SDL_SetColors(surface, colors, 0, 256);
}

you need to setpalette(area) before you fill it. currently it's interpreting the 15 as an RGB value, hence the dark red.
