same here! Well, but the problem that people see is, that actually the libstc++ of gcc 4.1 _should_ be compatible with the libstdc++ of gcc 3.x - well, but the gentoo-people are usually pessimistic about it :-) And actually some incompatibilities are already known, i think (but they didn't affect me *eg*) (actually there was an ABI-switch within th gcc3.x series, before gcc 3.4 i think)
