ANSI C++

ANSI C++

[Lothar Werzinger]

I downloaded the Snapshot from 971114 and trued to compile a program
that uses the new features of ANSI C++

 -- #includes with no '.h'
 -- namespaces
 -- the new iostream library.

and it failed to compile, as the iostream library is still the old one.
So my question is: Is there already a new iostream library for the gnu
compiler that works as described in the ANSI draft?

This is implemented for some headers but not for others.  Several folks
have donated patches to provide the missing ones, but it seems the patches
haven't been accepted.

Namespaces are not implemented, except that 

using namespace std;

is accepted and ignored, so that ANSI/ISO programs that use it will build
(but the standard classes are really in the global namespace).

This has not been done yet.

I understand that someone has written one, but it's not going to be ready
for the first egcs release.

What is missing besides namespaces ?
