Fixed bug 3517 - Compiler warnings with gcc -Wstrict-prototypes

Browse source 
felix

Compiling even a simple SDL2 'hello world' program with gcc -Wstrict-prototypes (GCC 6.2.1) results in warnings like:

/usr/include/SDL2/SDL_gamecontroller.h:143:1: attention : function declaration isn't a prototype [-Wstrict-prototypes]
 extern DECLSPEC int SDLCALL SDL_GameControllerNumMappings();
 ^~~~~~

It seems there is a missing 'void' between the parentheses.
