../../src/LyXView.h:38: `SigC' is not a class or namespace
../../src/LyXView.h:38: `Object' is not a class or namespace
../../src/LyXView.h:38: confused by earlier errors, bailing out
This happens due the use of namespaces in LyXView.h and BufferView_pimpl.h
(SigC::Object), while my compiler doesn't support namespaces.
