  fixes to get libardour building
  
  - can't cast away volatile, so copy _transport_frame before emitting it.
  - const_reverse_iterator::operator!=() isn't defined in this version of gcc.
  - removed annoying HERE WE ARE CAAudioFile.h #warning.
  - removed unnecessary include of sndfile.h in session.h.
  - we don't want to set -march=i686 on the mac, so indent this if-statement so
    it's only run on linux.
  - DEBUG_STR() fails in the NDEBUG case, so wrap its use in an #ifndef NDEBUG
........
  r6300 | trutkin | 2009-12-05 15:48:29 -0500 (Sat, 05 Dec 2009) | 2 lines
  
  remove old scons-style CXXFLAGS_FOO in favor of just CXXFLAGS
........
  r6301 | trutkin | 2009-12-05 16:01:10 -0500 (Sat, 05 Dec 2009) | 8 lines
  
  clean up configure flags
  
  - removed useless --aubio and --syslibs flags.  The syslibs value is ignored 
    as we don't bring our own libraries with us anymoreand we use aubio 
    automatically if it's available
  - added ways to turn off fpu_optimization and NLS
  - fixed compiling on the mac without fpu_optimization
........
  r6302 | trutkin | 2009-12-05 18:12:46 -0500 (Sat, 05 Dec 2009) | 5 lines
  
  go back to prior uselib method for COREAUDIO, AUDIOUNIT, and GTKOSX
  
  - fixed compile of CoreAudioSource
  - re-did inclusion of coremidi_midiport.cc to depend on COREAUDIO presence
........
  r6303 | trutkin | 2009-12-05 18:59:02 -0500 (Sat, 05 Dec 2009) | 5 lines
  
  fixed compiler warnings about classes with virtual member functions, but no virtual destructor.
  
  - Changed Metering to not use foo() = 0; to indicate it shouldn't be instantiated, but
    private: Metering(), which is more idiomatic.
........
  r6304 | trutkin | 2009-12-05 19:25:41 -0500 (Sat, 05 Dec 2009) | 2 lines
  
  TOP_MENUBAR isn't used when building ardour.menus.  Removed.
........
  r6305 | trutkin | 2009-12-05 19:46:11 -0500 (Sat, 05 Dec 2009) | 5 lines
  
  fix some AudioUnit compile errors
  
  - update AudioUnit to use ChanCount
  - fix some namespacing issues in audio_unit.h
........
  r6306 | trutkin | 2009-12-05 20:08:48 -0500 (Sat, 05 Dec 2009) | 2 lines
  
  make --extra-warn useful
........
  r6308 | trutkin | 2009-12-05 22:59:42 -0500 (Sat, 05 Dec 2009) | 10 lines
  
  fix compiling/linking with --coreaudio
  
  - rearrange ardour_ui.h header in editor.cc to avoid conflict
  - midi++ depends on OSX as well as COREAUDIO
  - fixed including frameworks
  - tweaked --extra-warn again.  it's kinda redundent with --strict
  - improved indentation in wscript
  - use #ifdef HAVE_COREMIDI, not #if HAVE_COREMIDI.  #if isn't interchangable
    with #ifdef and won't work if HAVE_COREMIDI is defined with no value.
