Thanks Thad! It feels to me that Windows dev setup is getting overly complicated. Is there still any reason not to upgrade to GCC 4.7? This would remove the need to do all that dance with component downgrades. BTW, this also affects users of official Rust releases (#8598<https://github.com/mozilla/rust/issues/8598> ).
I don't think build bot environment upgrades can be done via a PR, so we'll need help from someone on the core Rust team. Also, a new stage0 compiler snapshot will need to be cranked out because of #5878<https://github.com/mozilla/rust/issues/5878> .
