#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.
