Clever.

Typo, document.

Heh, I resisted telling Sam to make this change just a few hours ago.

I’ll land this once either EWS or my local build is done.

This change breaks the Windows build:

10>C:\Projects\WebKit\OpenSource\WebKitBuild\Release\obj32\WebCore\DerivedSources\WebKitFontFamilyNames.cpp(143): error C2440: 'static_cast' : cannot convert from 'const WTF::AtomicString *' to 'void *'
10>          Conversion loses qualifiers

Perhaps this was doing the wrong thing, and the C-style cast was masking the problem. But the build is now broken.

This may be related to the declaration of SKIP_STATIC_CONSTRUCTORS_ON_GCC, which is not active on Windows.

Any ideas for resolving this?

[Darin Adler]

Seems fine to change it back to a C-style cast.

According to http://andreaskling.com/~kling/sizes/r155849/WebCore.txt, this patch actually made HTMLNames::init bigger. Something is going wrong.
