[webkit-help] unresolved symbol errors on windows

[Cliff Moon]

I'm trying to build webkit on windows and I'm getting unresolved symbol 
errors during linking of javascriptcore.  In particular, the linker 
cannot find CharacterClass* wordcharCreate() and friends.  I found the 
headers defined in JavaScriptCore/yarr/RegexPattern.h, but I could not 
find an implementation for the functions anywhere in the project.  Where 
are these defined?  Is there an external library that I'm missing?
