Howdy,

I've been testing DJGPP 2.01 with some STL examples from "STL Tutorial
and Reference Guide." When I try to compile the following example:

// Ex02-02.cpp: Demonstrating an STL map.

#include <cstdlib>
#ifdef	__GNUC__
#	include <iostream.h>
#else
#	include <iostream>
#endif
#include <map>
#include <string>

int main()
{
	map<string, long, less<string> > directory;
	directory["Bogart"] = 1234567;
	directory["Bacall"] = 9876543;
	directory["Cagney"] = 3459876;
	// etc.

	// Read some names and look up their numbers.
	string name;
	while (cin >> name) 
    if (directory.find(name) != directory.end()) 
		cout << "The phone number for " << name
			 << " is " << directory[name] << "\n";
    else
		cout << "Sorry, no listing for " << name << "\n";

	return EXIT_SUCCESS;
}

With the following command:

gxx Ex02-02.cpp

I get the following errors:

What's wrong?

Thanks in advance....
