flightgear/auto_ptr.hxx
curt 5e6761d7da /Simulator/Objects/fragment.hxx
Nested fgFACE inside fgFRAGMENT since its not used anywhere else.

./Simulator/Objects/material.cxx
./Simulator/Objects/material.hxx
  Made fgMATERIAL and fgMATERIAL_MGR bona fide classes with private
  data members - that should keep the rabble happy :)

./Simulator/Scenery/tilemgr.cxx
  In viewable() delay evaluation of eye[0] and eye[1] in until they're
  actually needed.
  Change to fgTileMgrRender() to call fgMATERIAL_MGR::render_fragments()
  method.

./Include/fg_stl_config.h
./Include/auto_ptr.hxx
  Added support for g++ 2.7.
  Further changes to other files are forthcoming.

Brief summary of changes required for g++ 2.7.
  operator->() not supported by iterators: use (*i).x instead of i->x
  default template arguments not supported,
  <functional> doesn't have mem_fun_ref() needed by callbacks.
  some std include files have different names.
  template member functions not supported.
