#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.
