common.cc starts with:
#include <sys/types.h>
#include <sys/mman.h>
#include <ctype.h>

#if __GNUC__ > 3 || (__GNUC__ == 3 && __GNUC_MINOR__ >= 1)
#include <ostream>
#else
#include <ostream.h>
#endif

#include <iostream>
using namespace std;

#include "common.h"



gcc (g++) 3.0 shipped with headers without the ".h", except for ostream.
all others dropped the ".h" at gcc 2.95?
after gcc 3.1 all ".h" are gone.


maybe we need to extend these tests to be less gcc centric.


"ostream" != "iostream"

$ ll /usr/include/c++/3.3/ | grep stream
-rw-r--r--  1 root root 24834 May 25  2005 fstream
-rw-r--r--  1 root root  3041 May 25  2005 iostream
-rw-r--r--  1 root root 27292 May 25  2005 istream
-rw-r--r--  1 root root 18353 May 25  2005 ostream
-rw-r--r--  1 root root 20575 May 25  2005 sstream
-rw-r--r--  1 root root 31972 May 25  2005 streambuf

but iostream #includes both <istream> and <ostream>
