Beyond the requirements of JSStringRef.h (eg. that a few types exist)  
there should not be any deliberate dependency on CF in JSC for  
anything other than platform specific behaviour, and a quick scan  
indicates that all such sites seem to have appropriate ifdef guards.

On non-CF platforms you also only want to include JavaScriptCore/ 
JavaScript.h not JavaScriptCore/JavaScriptCore.h as it is  
JavaScriptCore.h that brings in the CF APIs.  The only real concern  
beyond that is to make sure that in builds where you do not want a CF  
dependency in JSC to ensure that PLATFORM(CF) is false and that  
JSStringRefCF.cpp is not compiled.

In an ideal world that should Just Work.
