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) --------------enigABCF763DE66139C707FABE91 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.1 (Cygwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEvjGu7Ww7FjRBE4ARAjbcAKDqXqgR83nnI5jtmtMgE9D2ZbgwnwCfXWWU Qo4dZ9mMhZUnvCJg9+Il3y8= =7YWN -----END PGP SIGNATURE----- --------------enigABCF763DE66139C707FABE91-- -- gentoo-user@gentoo.org mailing list
