cout instead of FCGX_FPrintF (c++)

Tim Wood encourage me (thank you Tim!) to present my solution of the task.
Here it is. 
I please (all of you) to comment it as I realize the solution has many holes:

Waldemar Biernacki

=================================================
#include <stdlib.h>
#include <iostream>
#include <string>

#include "fcgi_config.h"
#include "fcgiapp.h"

using namespace std;

extern char **environ;

FCGX_Stream *in, *out, *err;

FCGX_Stream & operator<<( FCGX_Stream &o, const char * s ) {
	FCGX_FPrintF ( out, s );
	return o;
}
FCGX_Stream & operator<<( FCGX_Stream &o, string s ) {
	FCGX_FPrintF ( out, s.c_str() );
	return o;
}
FCGX_Stream & operator<<( FCGX_Stream &o, int s ) {
	FCGX_FPrintF ( out, "%d", s );
	return o;
}

int main () {
	FCGX_ParamArray envp;

	int count = 0;
	while ( FCGX_Accept ( &in, &out, &err, &envp ) >= 0 ) {
		*out << "Content-type: text/html\r\n\r\n"
			<< "<br> Request: "<< ++count <<" <br>";
		string some_string = "Now we are testing strings... \n";
		*out << "<br> " << some_string << "\n"
			<< "<br>... Finish!";
	}
	return 0;
}
