Anyone who can help on this?
I am trying to use command line options in my program.  Here's what I've got
so far:

int main(int argc, char* argv[])
{
// Declare/init. variables
int title_on;

// Command line option procedure
if (argc == 1)
{
  title_on = 1;
}
else
{
  if (argv[1] == "/nts")
   title_on = 0;
  else if (argv[1] == "/?")
  {
   puts("Command line options");
   puts("-----------------------");
   puts("/?  Display this list");
   puts("/nts No title screen");
   return 0;
  }
  else
  {
   puts("Invalid command line option.  Use \"/?\" to see valid options.");
   return 0;
  }
}

The problem is that whenever one of the valid options is entered, the
comparison statements (such as--if (argv[1] == "/nts")) don't work.  In
other words, even though argv[1] DOES equal "/nts", the program goes past
the "if" statement as if it didn't.  Am I overlooking the obvious here, or
is my compiler screwed?  BTW, I'm using DJGPP & RHIDE.  All help is greatly
appreciated.
