PLATFORM(MAC) build broken with HAVE(ACCESSIBILITY) disabled

[David Kilzer (:ddkilzer)]

If HAVE(ACCESSIBILITY) is set to zero in JavaScriptCore/wtf/Platform.h, the PLATFORM(MAC) build will fail.  I have a patch to fix this.

In cases like this I prefer to leave the class definition cleaner by putting the inline function definition after it. Like this:

    #if !HAVE(ACCESSIBILITY)
    inline bool AccessibilityObject::accessibilityIgnoreAttachment() const
    {
        return true;
    }
    #endif

This patch seems fine as-is.

That doesn't work:

/Volumes/Data/WebKit.git/WebCore/page/AccessibilityObject.h:398: error: ‘bool WebCore::AccessibilityObject::accessibilityIgnoreAttachment() const’ and ‘bool WebCore::AccessibilityObject::accessibilityIgnoreAttachment() const’ cannot be overloaded

I've done it before, so I know it works. I think there was some other small mistake that caused this. I'll try it myself later.

I think it would work to add the function definition to WebCore/page/AccessibilityObject.cpp instead.  Was that what you meant?

I agree that would also work, but the function wouldn't be inline in that case.

No, it was not what I meant.
