building g++

[Homer Neal]

To whom it may concern,

I've been trying to install g++ on an alpha-dec-osf4.0d system.
After following all the steps I've tried compiling routines that
I know compile on other alpha systems but it fails in iostream and
streambuf on mine. To illustrate the problem I've created the
simplest example:

#include <iostream.h>

void main()
{
   cout << "Testing\n";
}

If I then do g++ 
 test.cpp -o testcpp

I get the following error messages:
/group/ppg/prj/lcd/egcs/local/include/g++/streambuf.h:238: new
declaration `void * ios::pword(int)'
/group/ppg/prj/lcd/egcs/local/include/g++/streambuf.h:237: ambiguates

Could you please give me some hints as to what might have gone wrong
when I built g++.

By the way, I used 
  egcs-1.1.1.tar.gz
to build it.

Many thanks for any help you may offer.
