Function fatal() declared twice

I was checking the return status if SSE2 is not available and I noticed that the fatal() function is defined twice in util.cc:

void fatal(const char * msg)
{
  fprintf(stderr, "\nError: %s\n", msg);
  exit(1);
}

void fatal(const char * format, const char * message)
{
  fprintf(stderr, "\n");
  fprintf(stderr, format, message);
  fprintf(stderr, "\n");
  exit(1);
}

That's the same thing in vsearch. Maybe that's normal?

Yes, it is perfectly ok. They are two different functions with the same name, but different number of arguments. The correct function is selected based on the number and types of arguments.

Thanks, I didn't know this was possible.
