FYI, my emerge.log says that stage1 cross-x86_64-w64-mingw32/gcc-11.1.0 was successfully built on my environment (on Jun 10, 2021).

I would recommend you try again with more default-ish USE flags. Or at least with USE=-lto.

[Comment 4 James Beddek 2021-12-01 00:46:00 UTC]

I've since removed 'lto pgo' from the USE flags, and it still fails for 11.2.0. This is just a bootstrapping failure as known in the upstream bug. Bootstrapping succeeds for 10.3.0-r2, but I'm running into another old bug: https://bugs.gentoo.org/827923 https://bugs.gentoo.org/513706
