Title:
  friend class Notify::self_type; doesn't work with clang

Status in Hugin - Panorama Tools GUI:
  Fix Committed

Bug description:
  I tried to compile hugin 2012.0.0 (but sources of the latest version
  are still the same) on Mac OS X 10.7 with Xcode 4.6.3 and clang (Apple
  LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn)). One of the
  problems is with the file src/foreign/vigra/vigra/cachedfileimage.hxx
  and the following chunk of code:

   class NotifyingDirectionSelector<UnstridedArrayTag, T, Notify>
   {
   #ifdef __GNUC__
   friend class Notify::self_type;
   #else
   friend typename Notify::self_type;
   #endif

  The compiler entered the first part of #ifdef and refused to compile
  "friend class Notify::self_type;". The other code (friend typename
  Notify::self_type;) was happily accepted, but I'm not sure what the
  proper patch should be / how to modify "#ifdef __GNUC__" to redirect
  clang to the #else part.
