[webkit-dev] Origin of S60WebKit?

Hi, I am trying to port S60WebKit to resource constraint embedded Linux system based on S3C2410. At very early stage, I have following two radical questions. Can anyone give me hints? 1. There seems to be a big difference between the latest source code of WebKit and S60WebKit. What version (or point of time) did S60WebKit based on? I want to get the original source code of WebKit which S60 project had been based on. 2. From the source code, I discovered that NOKIA team disabled pthread support in KJS. Though I know nothing about Symbian, I am sure that they could port to Symbian's threading model if they want. Does anyone know the reason? If I re-enable pthread code, may I expect threading support without any problem? Thanks, Kenneth
