To begin with, I understand that you, libstdc++ developers, have as target
to develop a final version 3 g++; but you also, please, understand that
somebody in the real world is developing for multiplatform environments
(for me Linux, Solaris, Compaq and Irix) and must use a modern standard
library as possible compliant with ISO/IEC 14882-1998.  The first
announcement I have seen for gcc v3 was for spring 2000.

libstdc++ 2.91 is an official snapshot of the standard library.  Well, you
may OR state that it is unusable, or give CLEAR INSTRUCTIONS about how to
use it.  Your web page asserts that it is usable with a 2.97 snapshot and
gives installation instructions.

For this particular problem, here are the details: gcc/g++ has been built
following STEP BY STEP the instructions in the libstdc++ web page, with
the statements:

cd ~/work
gzip -dc /usr/archive/dist/gcc-20010115.tar.gz | tar xof -
cd gcc-20010115
gzip -dc /usr/archive/dist/libstdc++-2.91.tar.gz | tar xof -
rm -rf libstdc++-v3
mv libstdc++-2.91 libstdc++-v3
cd ..
mkdir objdir && cd objdir
../gcc-20010115/configure --prefix=/usr/local/gcc --enable-libstdcxx-v3
make bootstrap
make -k check

The part of "make check" relevant to libstdc++ shows:
Detailed test results in ./testsuite/20010119-mkcheck.txt

After a "make install" and a chenge in PATH, LD_LIBRARY_PATH and so on in
order to use this gcc-20010115 + libstdc++-2.91 environment, the following
well known program gives:

MLO@mlinux 11 $ cat hello.cxx
#include <iostream>

int main() {
  std::cout << "Hello, world!" << std::endl;
}
MLO@mlinux 12 $ g++ -ansi -Wall -fhonor-std -g -o hello hello.cxx

Tha last usable libstdc++ I have is 2.90.8 built with gcc 2.95.2.1 .
