+Subject: [PATCH] chrome/browser: Replace some forward declarations with actual
+ includes
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This fixes the GCC build which was failing like this:
+
+    ../../base/scoped_observer.h: In instantiation of ‘void ScopedObserver<Source, Observer>::RemoveAll() [with Source = TabStripModel; Observer = TabStripModelObserver]’:
+    ../../base/scoped_observer.h:26:5:   required from ‘ScopedObserver<Source, Observer>::~ScopedObserver() [with Source = TabStripModel; Observer = TabStripModelObserver]’
+    ../../chrome/browser/ui/views/extensions/extension_popup.h:115:70:   required from here
+    ../../base/scoped_observer.h:45:20: error: invalid use of incomplete type ‘class TabStripModel’
+           sources_[i]->RemoveObserver(observer_);
+           ~~~~~~~~~~~~~^~~~~~~~~~~~~~
+
+This is caused by https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89311 ("Brace
+initialization needlessly invokes destructor"), i.e. having something like
+
+    ScopedObserver<T, U> observer_{this};
+
+in a header declaration requires T and U to be fully declared because
+ScopedObserver's destructor references them. In a few cases, T was only
+forward-declared.
