#ifndef __STL_CONFIG_H
# define __STL_CONFIG_H

// What this file does.
//  (1)  Defines bool, true, and false if the compiler doesn't do so already.
//  (2)  Defines __STL_NO_DRAND48 if the compiler's standard library does
//       not support the drand48() function.
//  (3)  Defines __STL_STATIC_TEMPLATE_MEMBER_BUG if the compiler can't 
//       handle static members of template classes.
//  (4)  Defines 'typename' as a null macro if the compiler does not support
//       the typename keyword.
//  (5)  Defines __STL_CLASS_PARTIAL_SPECIALIZATION if the compiler 
//       supports partial specialization of class templates.
//  (6)  Defines __STL_FUNCTION_TMPL_PARTIAL_ORDER if the compiler supports
//       partial ordering of function templates (a.k.a partial specialization
//       of function templates.
//  (7)  Defines __STL_EXPLICIT_FUNCTION_TMPL_ARGS if the compiler
//       supports calling a function template by providing its template
//       arguments explicitly.
//  (8)  Defines __STL_MEMBER_TEMPLATES if the compiler supports
//       template members of classes.
//  (9)  Defines 'explicit' as a null macro if the compiler does not support
//       the explicit keyword.    
//  (10) Defines __STL_LIMITED_DEFAULT_TEMPLATES if the compiler is
//       unable to handle default template parameters that depend on
//       previous template parameters.
//  (11) Defines __STL_NON_TYPE_TMPL_PARAM_BUG if the compiler has 
//       trouble performing function template argument deduction for
//       non-type template parameters.
//  (12) Defines __SGI_STL_NO_ARROW_OPERATOR if the compiler is unable
//       to support the -> operator for iterators.
//  (13) Defines __STL_USE_EXCEPTIONS if the compiler (in the current
//       compilation mode) supports exceptions.
//  (14) Define __STL_USE_NAMESPACES if we're putting the STL into a 
//       namespace.  
//  (15) Defines __STL_SGI_THREADS if this is being compiled on an SGI
//       compiler, and if the user hasn't selected pthreads or no threads
//       instead.
//  (16) Defines __STL_WIN32THREADS if this is being compiled on a 
//       WIN32 compiler in multithreaded mode.
//  (17) Define namespace-related macros (__STD, __STL_BEGIN_NAMESPACE, etc.)
//       apropriately.
//  (18) Define exception-related macros (__STL_TRY, __STL_UNWIND, etc.)
//       appropriately.
//  (19) Defines __stl_assert either as a test or as a null macro,
//       depending on whether or not __STL_ASSERTIONS is defined.
