Fair.  I knew there was some reason why we were not using -std=c++0x (really -std=gnu++0x) directly.  (Mozilla as a whole uses it, SpiderMonkey as a specific component doesn't.)  But nobody seems to know or remember what it was when I just asked.  I'll investigate this to see whether this is more feasible than I thought, then post back after getting those results.
