Thanks a lot, Ben.  I'm really trying.

OK, now I know better.  (So IS there a list for v2?)

Anyway, I successfully built v3, including the gcc rebuild, but my
libraries are all messed up now.  Is there anyone who's willing to help
me?  I have a vanilla Red Hat 6.0 system, plus the gcc-2.95 devel RPMs,
plus v3.  A simple hello.cpp program generates the following on compile:

And your hard work is greatly appreciated.  I can't *imagine* installing
without your docs!  I've read them and reread them numerous times to get
things straight.  (Let me know if you want specific comments.)

Anyway, thanks for your response.

p.s.  After I installed v3, I found that
/usr/lib/libstdc++-libc6.1-1.so.2
      had been removed.  I couldn't find any reference to that file in
the
      v3 source tree, but it could have been wiped by one of the 2.95.2
      RPMs.  Unfortunately it's needed for groff, which is used by
man(1).
      Anyway, any help is appreciated; if the problem was caused by some
      other install, I apologize in advance for bothering you.

$ man g++
