        - fixed problems preventing us from compiling with gcc 4.0

        * WebCore.pbproj/project.pbxproj: Removed -fobjc-exceptions because I can't figure out an easy
        way to pass it only when compiling Objective-C/C++. Removed -Wmissing-prototypes from
        WARNING_CPLUSPLUSFLAGS since it's now a C-only warning.

        * khtml/css/parser.y: Changed some rules that were using a float to pass around an enum to use an
        int instead to avoid a warning.
        * khtml/css/parser.cpp: Regenerated.
        * khtml/css/parser.h: Regenerated.

        * khtml/ecma/kjs_dom.cpp: (DOMTextProtoFunc::tryCall): Rearranged a return statement to avoid an incorrect
        warning.
        * khtml/ecma/kjs_html.cpp: (KJS::Context2DFunction::tryCall): Initialized a couple of variables to avoid
        an incorrect warning.
        * khtml/ecma/kjs_proxy.cpp: (KJSProxyImpl::evaluate): Rearranged how we exit from the function to avoid
        an incorret warning.
        * khtml/editing/selection.cpp: (khtml::Selection::debugPosition): Changed some %d to %ld where the
        parameters where long ints.
        * khtml/editing/visible_position.cpp: (khtml::VisiblePosition::debugPosition): Ditto.
        * khtml/xml/dom_position.cpp: (DOM::Position::debugPosition): Ditto.
        * kwq/DOMEvents.mm: (-[DOMMouseEvent initMouseEvent:::::::::::::::]): Rearranged code to avoid a cast
        that was causing an incorrect warning.
        * kwq/DOMUtility.mm:
        (createObjCDOMNode): Broke out as a separate function.
        (KJS::ScriptInterpreter::createObjcInstanceForValue): Rearranged code to avoid a namespace collision with
        KJS::DOMNode and the Objective-C DOMNode class.
        * kwq/KWQFileButton.mm: Made fields of KWQFileButtonAdapter public to avoid an error, new to gcc 4.0,
        about accessing protected Objective-C fields.
        * kwq/KWQKHTMLPart.mm:
        (KWQKHTMLPart::matchLabelsAgainstElement): Rearranged a return statement to avoid an incorrect warning.
        (KWQKHTMLPart::imageFromRect): Rearranged how this function does its exception handling to avoid a
        "may be clobbered" warning.
        * kwq/KWQKJavaAppletWidget.mm: Fixed incorrect import that said "KHTMLView.h" instead of "khtmlview.h".
        * kwq/KWQObject.mm: Made fields of KWQObjectTimerTarget public to avoid an error, new to gcc 4.0,
        about accessing protected Objective-C fields.
        * kwq/WebCoreBridge.mm: (partHasSelection): Used [bridge part] instead of getting directly at instance
        variable to avoid an error, new to gcc 4.0, about accessing protected Objective-C fields.

        * WebCore-combined.exp: Regenerated.
        * WebCore-tests.exp: Added some additional symbols needed by the tests under gcc 4.0.
