NeXT donated their Objective-C compiler (which they were obligated to do
under the terms of the Gnu Public License) and it is distributed with
gcc-2.x.  However, they did not donate the run-time support or the class
libraries.  If you have a NeXT, you have these libraries and should be
able to use the Objective-C compiler from Gnu (no, I haven't tried it); if
you're on another platform, you can't (yet), because key parts are
missing.  I understand that there is now a group working on remedying
this.

g++ is a fairly complete implementation.  It supports templates, though
there are still some bugs.  We successfully use it for fairly sizable
projects on several platforms (Sun-4, DecStation, HP Snake, not NeXT though).

>3)	How stable is 2.2.2? 

It's possible to make it dump core, but that's getting harder all the
time.  It's closer to the ARM than cfront 2.1 is, and not as close to
the ARM as cfront 3.0.

As of libg++ 2.0, the iostream library is very close to that of AT&T.
Yes, ANSI is going to specify standard libraries for streams, and possibly
a couple of others.  I think you mean "In interface, not implementation",
since you don't care about the implementation if the interface is the same.

I recommend getting gdb-4.6 if you're going to use g++.  It has greatly
improved facilities for finding member functions, including command
completion (where you type part of the name and prototype of an overloaded
member function and it completes it or lists the possibilities).  I don't
know what version of gdb NeXT provides; if it predates 4.0 you'll need
to upgrade.
