>Description:
a function declared as taking no arguments accepts infinite arguments without complaint under -Wall -ansi -pedantic or any other standard 

eg;
void test( ) {
  printf("shouldn't compile\n");
}

int main(void) {
  test( 1, 2, 3, "Hello", "World", "this", "shouldn't", "compile" );
  return(0);
}

above code compiles and runs without error
>How-To-Repeat:
sample code:

#include <stdio.h>

void test( ) {
  printf("shouldn't compile\n" );
}

int main(void) {
  test( 1, 2, 3, "Hello", "World" );
  return(0);
}
>Fix:
change prototype of function that shouldn't accept arguments
to use void as argument

eg;
void test(void);
