I'm afraid I can not agree with you. Speaking for MICO project gcc3.0 was
broken compiler (remember virtual inheritance issues?) and was even broken
still in its fourth incarnation (gcc3.0.4) when we do not count with the
patch which was loaded into the contrib directory IIRC, but not integrated
into the compiler that time. So yes, for MICO first usable 3.x was 3.1.

Here I agree with you. C++ in GCC is really better and better every year.
Thanks to all you working on such nice compiler!
