I had mistakenly changed the stub ResourceRequest.h for Curl-based WebKit from my original dummy structure to a void*, believing that this worked just as well. Unfortunately, I had not properly rebuilt, so my original structure-based implementation was still being used in the WebKit.dll build. When I retrieved the updated sources with my 'new' change and rebuild, I found that WebKit.dll would not compile due to conflict between the definition in WebKit.h. The attached patch returns to my original dummy structure, which satisfies the compiler dependencies set by the WebKit.idl interface.
