#ifndef __STL_CONFIG_H
# define __STL_CONFIG_H

// Flags:
// * __STL_NO_BOOL: defined if the compiler doesn't have bool as a builtin
//   type.
// * __STL_HAS_WCHAR_T: defined if the compier has wchar_t as a builtin type.
// * __STL_NO_DRAND48: defined if the compiler doesn't have the drand48 
//   function.
// * __STL_STATIC_TEMPLATE_MEMBER_BUG: defined if the compiler can't handle
//   static members of template classes.
// * __STL_CLASS_PARTIAL_SPECIALIZATION: defined if the compiler supports
//   partial specialization of template classes.
// * __STL_PARTIAL_SPECIALIZATION_SYNTAX: defined if the compiler 
//   supports partial specialization syntax for full specialization of
//   class templates.  (Even if it doesn't actually support partial 
//   specialization itself.)
// * __STL_FUNCTION_TMPL_PARTIAL_ORDER: defined if the compiler supports
//   partial ordering of function templates.  (a.k.a partial specialization
//   of function templates.)
// * __STL_MEMBER_TEMPLATES: defined if the compiler supports template
//   member functions of classes.
// * __STL_MEMBER_TEMPLATE_CLASSES: defined if the compiler supports 
//   nested classes that are member templates of other classes.
// * __STL_EXPLICIT_FUNCTION_TMPL_ARGS: defined if the compiler 
//   supports calling a function template by providing its template
//   arguments explicitly.
// * __STL_LIMITED_DEFAULT_TEMPLATES: defined if the compiler is unable
//   to handle default template parameters that depend on previous template
//   parameters.
// * __STL_NON_TYPE_TMPL_PARAM_BUG: defined if the compiler has trouble with
//   function template argument deduction for non-type template parameters.
// * __SGI_STL_NO_ARROW_OPERATOR: defined if the compiler is unable
//   to support the -> operator for iterators.
// * __STL_USE_EXCEPTIONS: defined if the compiler (in the current compilation
//   mode) supports exceptions.
// * __STL_USE_NAMESPACES: defined if the compiler has the necessary
//   support for namespaces.
// * __STL_NO_EXCEPTION_HEADER: defined if the compiler does not have a
//   standard-conforming header <exception>.
// * __STL_SGI_THREADS: defined if this is being compiled for an SGI IRIX
//   system in multithreaded mode, using native SGI threads instead of 
//   pthreads.
// * __STL_WIN32THREADS: defined if this is being compiled on a WIN32
//   compiler in multithreaded mode.
// * __STL_LONG_LONG if the compiler has long long and unsigned long long
//   types.  (They're not in the C++ standard, but they are expected to be 
//   included in the forthcoming C9X standard.)


// User-settable macros that control compilation:
// * __STL_USE_SGI_ALLOCATORS: if defined, then the STL will use older
//   SGI-style allocators, instead of standard-conforming allocators,
//   even if the compiler supports all of the language features needed
//   for standard-conforming allocators.
// * __STL_NO_NAMESPACES: if defined, don't put the library in namespace
//   std, even if the compiler supports namespaces.
// * __STL_ASSERTIONS: if defined, then enable runtime checking through the
//   __stl_assert macro.
// * _PTHREADS: if defined, use Posix threads for multithreading support.
// * _NOTHREADS: if defined, don't use any multithreading support.  


// Other macros defined by this file:

// * bool, true, and false, if __STL_NO_BOOL is defined.
// * typename, as a null macro if it's not already a keyword.
// * explicit, as a null macro if it's not already a keyword.
// * namespace-related macros (__STD, __STL_BEGIN_NAMESPACE, etc.)
// * exception-related macros (__STL_TRY, __STL_UNWIND, etc.)
// * __stl_assert, either as a test or as a null macro, depending on
//   whether or not __STL_ASSERTIONS is defined.
