First problem: main MUST ALWAYS RETURN AN int!  Second problem the first 
argument to main() is an int not a short!  Third, in general argc is 
pretty useless without argv so... main should be: 

int main( int argc, char **argv )

Last problem, since the linker expects main to return an int your return 
MUST return something:

   return 0;
