If you receive this message from the avr-gcc list, please reply also to this 
address,
because it is not on the avr-gcc mailing list.

Yes that's true, I will think about it.
But before I can make RPMs I need to write the needed patches and for this
I need the answers to my original questions.

In the meantime I have a c++ compiler, but I haven't tested it (libc and 
startup file still missing).
There was a small patch necessary to tell configure not to build libiberty, but 
this was simple.

Tomorrow I will not try to build the avr libc. I have seen that this is not 
build with the auto tools.
So I think I will write the autoconf/automake scripts, if nobody else has done 
this until now.

Here are some parts of the original message again:

I used the official versions of binutils (2.11.2) and gcc (3.0.2).
I have started with the binutils followed by gcc (C and C++).
There were no problems until now except for some warnings in binutils and gcc.

First question:
Shall I fix this warnings or are they already fixed in CVS (havent' looked
there) or is someone else working on this subject?

Next questions:
How far is the C++ part for avr?
I am not so familar with the compiler internals, but I think if the backend 
for C is ready it is possible to use also C++. Maybe the startup code must be
changed to call all con/destructors of global objects. But I don't know it in
detail. Maybe it is already done in libgcc. Any hints?

Is there a gnu simulator available for the avr or is someone working on it?

I know about avr-gdb-4.18. Shall I try to port gdb-5.0 for avr or is someone
else working on it?
