The double rounding problem even occurs between different versions of gcc. I think ultimately we should put our foot down and ship with sse2 enabled (not possible for 2.7 though, unless an LTS-PEP emerges). If distributions want to break that, it's their business. :) The gcc manual is quite upfront about the issue and really recommends sse2 for reproducible results.
