I'm not sure why this is still building successfully on tbpl; it certainly isn't building locally.

I think you want to have USE_CXX11= as well here.

When filing bugs like this, it would be useful to have a trace of your build errors. TBPL not failing to build is maybe evidence that something is wrong with your toolchain, which doesn't necessarily grant this change.

BTW, neither clang 3.4 nor gcc 4.8 fail to build standalone js on linux for me. I'm tempted to back this out.

I spoke too quickyl, I got an error with clang, which, interestingly, has not much to do with C++11... and is actually a real bug in the code.

Backed out.

I think this broke the OS X Opt SpiderMonkey build:

https://tbpl.mozilla.org/?tree=Mozilla-Inbound&showall=1&rev=5939320824b1&jobname=spidermonkey

Looks like a Clang/LLVM crash..

Most likely because of bug 895208.
