Can't create executable for running SDL game in windows(error: previous declaration of SDL_main was ...)

I've created a game with SDL2 library in ubuntu with the atom editor, and for compiling created a makefile with this code:

game: main.c LoadGame.c Events.c CreateTex.c CollisionDetection.c Render.c gameStatus.c
    gcc main.c LoadGame.c Events.c CreateTex.c CollisionDetection.c Render.c gameStatus.c -w -lSDL2 -lSDL2_image -lSDL2_mixer -lSDL2_ttf -o game -lm -I.

And now I want to create an .exe so I created this makefile:

game: main.c LoadGame.c Events.c CreateTex.c CollisionDetection.c Render.c gameStatus.c
    i686-w64-mingw32-gcc main.c LoadGame.c Events.c CreateTex.c CollisionDetection.c Render.c gameStatus.c -w -lSDL2 -lSDL2_image -lSDL2_mixer -lSDL2_ttf -o game.exe -lm -I.

but it gives this error:


    In file included from /usr/i686-w64-mingw32/include/SDL2/SDL.h:32:0,
                     from main.c:2:
    main.c:8:5: error: conflicting types for ‘SDL_main’
     int main(int argc, char const *argv[]){
         ^
    /usr/i686-w64-mingw32/include/SDL2/SDL_main.h:117:39: note: previous declaration of ‘SDL_main’ was here
     tern C_LINKAGE SDLMAIN_DECLSPEC int SDL_main(int argc, char *argv[]);
                                         ^~~~~~~~
    makefile:5: recipe for target 'game' failed
    make: *** [game] Error 1

So I'd like some help so I can create a single .exe file from my sourcecode to run it in windows,while

Okay so, as keltar mencioned it looks like the problem was that in my program, 

int main(int argc, char const *argv[])
the argv array was constant which as stated in here it won't work. So the correct code would be:


    int main(int argc, char *argv[])
