// What this file does.
//  (1) Defines macros for some STL includes which may be affected
//      by file name length limitations.
//  (2) Defines macros for some features not supported by all C++ compilers.
//  (3) Defines 'explicit' as a null macro if the compiler doesn't support
//      the explicit keyword.
//  (4) Defines 'typename' as a null macro if the compiler doesn't support
//      the typename keyword.
//  (5) Defines bool, true and false if the compiler doesn't do so.
//  (6) Defines _FG_EXPLICIT_FUNCTION_TMPL_ARGS if the compiler
//      supports calling a function template by providing its template
//      arguments explicitly.
//  (7) Defines _FG_NEED_AUTO_PTR if STL doesn't provide auto_ptr<>.

//
// Revision 1.2  1998/09/10 19:07:04  curt
// /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.
