Can run Sdl with 32 bit headers but not with 64 bit headers

Here we go

#define SDL_MAIN_HANDLED
#include <SDL.h>
#include <stdio.h>
#include <string>

const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;

int main(int argc, char* argv[])
{
    SDL_Window* window = NULL;

    SDL_Surface* screenSurface = NULL;

    if( SDL_Init( SDL_INIT_VIDEO ) < 0 )
    {
        printf( "SDL could not initialize! SDL_Error: %s\n", SDL_GetError() );
    }
    else
    {
        window = SDL_CreateWindow( "Gaming", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN );
        if( window == NULL )
        {
            printf( "Window could not be created! SDL_Error: %s\n", SDL_GetError() );
        }
        else
        {
            screenSurface = SDL_GetWindowSurface( window );

            SDL_FillRect( screenSurface, NULL, SDL_MapRGB( screenSurface->format, 0xFF, 0xFF, 0xFF ) );     
            
            SDL_UpdateWindowSurface( window );
            
            SDL_Delay( 4000 );
        }
    }

    SDL_DestroyWindow( window );

    SDL_Quit();

    return 0;
}

This is my code, a simple window, I compile it using this command

g++ src/*.cpp -Iinclude -Llib -w -Wl,-subsystem,windows -lmingw32 -lSDL2main -lSDL2 -o Main

So is there any chance I can make it 64 bit header compatible? Or do i need to stick to 32 bit?
