This patch looks good. I have some minor nits.

Nit: tha => than

Nit: There is whitespace at the beginning of this line.

I know that this isn't part of your patch. We should consider renaming this function so that its name conforms to the WebKit style guide. Similarly, the names of many static functions in this file don't conform to the style guide. We can do such renames in a separate patch.

I know that this isn't part of your patch. From my understanding of (15) of section Names of the WebKit style guide (http://www.webkit.org/coding/coding-style.html), macro functions should be named like functions. In particular, they should use CamelCase, where the first letter is capitalized. That being said, I've seen macro functions, like this one, that use an all-caps naming notation with underscores for spaces in our code base.

> Source/WebCore/css/MediaQueryEvaluator.h:78
>  } // namespace

Nit: This comment should read "namespace WebCore".

dashes or underscores? I'm guessing these should be consistent.

Thanks for rolling this out for me. I’ll retest and find out what I screwed up.

At some point, we fixed the style resolver to not allocate these on the heap, so closing.
