Currently trunk fails to compile on Qt/WinCE : ..\..\..\WebCore\platform\text\TextBoundaries.cpp(48) : error C3861: 'isAlphanumeric': identifier not found ..\..\..\WebCore\platform\text\TextBoundaries.cpp(60) : error C3861: 'isAlphanumeric': identifier not found Thats because there is no isAlphanumeric function in WinCE, not by that name. There is a IsCharAlphaNumeric [0] function which is defined in winbase.h [0] http://msdn.microsoft.com/en-us/library/aa910686.aspx
Fixed in SVN.
