--- Comment #8 from Arseny Solokha <asolokha at gmx dot com> --- (In reply to Alexander Monakov from comment #7) > It appears you are building via portage and thus have Gentoo patches applied? Yes, I build weekly snapshots via Portage for convenience. But I use modified toolchain.eclass, and of course never apply Gentoo patches to them. My snapshots are vanilla. Gentoo's unpatched toolchain.eclass adds custom branding, among other things, which can be seen in -v output from my system compiler (compare it w/ the one from snapshot in comment 3): % gcc -v Using built-in specs.
