Resending, likely caught by filters.

Hi,
Please do a link time test instead, I am not getting this error and
would like to keep stack protector on.

The test case below will trigger ___stack_chk_guard to emit.

int main(){
  int i = 0;
  char a[1000];
  while(1){
    a[i] = 0;
    i++;
  }
}
 "i686-w64-mingw32-gcc -D_FORTIFY_SOURCE=2 -fstack-protector --param
ssp-buffer-size=4 -v" shows that libssp is already added.

Alternatively, to include __stack_chk_fail, use:

extern void __stack_chk_guard();
extern void __stack_chk_fail();

int main(){
void (*ssp[]) = {
  __stack_chk_guard,
  __stack_chk_fail
};

return 0;
}
