This is a known problem with Yosemite right now: servo/mozjs#19

I'd be willing to accept a patch to the configure script to tide us over until #4338 is fixed, since the upgraded version does not have this problem.

[jdm]

That being said, apparently brew uninstall apple-gcc42 fixes this.

[th0114nd]

I can confirm that brew uninstall apple-gcc42 allows compilation to go through.

[mseri]

I can confirm that brew uninstall apple-gcc42 allows compilation to go through.

[frewsxcv]

Does it seem fair to close this now?

[jdm]

Yep. We upgraded spidermonkey so this shouldn't be an issue any longer.
