#ifndef BOOST_CONFIG_HPP
#define BOOST_CONFIG_HPP

#define BOOST_VERSION 102400

//  BOOST_VERSION % 100 is the sub-minor version
//  BOOST_VERSION / 100 % 1000 is the minor version
//  BOOST_VERSION / 100000 is the major version


//  Conformance Flag Macros  -------------------------------------------------//
//
//  Conformance flag macros should identify the absence of C++ Standard 
//  conformance rather than its presence.  This ensures that standard conforming
//  compilers do not require a lot of configuration flag macros.  It places the
//  burden where it should be, on non-conforming compilers.  In the future,
//  hopefully, less rather than more conformance flags will have to be defined.

//  BOOST_NO_CV_SPECIALIZATIONS: if template specializations for cv-qualified
//  types conflict with a specialization for unqualififed type.

//  BOOST_NO_CV_VOID_SPECIALIZATIONS: if template specializations for cv-void
//  types conflict with a specialization for void.

//  BOOST_NO_ARGUMENT_DEPENDENT_LOOKUP: Compiler does not implement
//  argument-dependent lookup (also named Koenig lookup); see std::3.4.2
//  [basic.koenig.lookup]

//  BOOST_NO_DEPENDENT_TYPES_IN_TEMPLATE_VALUE_PARAMETERS: Template value
//  parameters cannot have a dependent type, for example
//  "template<class T, typename T::type value> class X { ... };"

//  BOOST_NO_EXPLICIT_FUNCTION_TEMPLATE_ARGUMENTS: Can only use deduced
//  template arguments when calling function template instantiations.

//  BOOST_NO_INCLASS_MEMBER_INITIALIZATION: Compiler violates std::9.4.2/4. 

//  BOOST_NO_INT64_T: <boost/cstdint.hpp> does not support 64-bit integer
//  types.  (Set by <boost/cstdint.hpp> rather than <boost/config.hpp>).

//  BOOST_NO_INTEGRAL_INT64_T: int64_t as defined by <boost/cstdint.hpp> is
//  not an integral type.

//  BOOST_NO_LIMITS_COMPILE_TIME_CONSTANTS: constants such as
//  numeric_limits<T>::is_signed are not available for use at compile-time.

//  BOOST_NO_MEMBER_TEMPLATES: Member template functions not fully supported.
//  Also see BOOST_MSVC6_MEMBER_TEMPLATES in the Compiler Control section below.

//  BOOST_NO_MEMBER_TEMPLATE_FRIENDS: Member template friend syntax
//  ("template<class P> friend class frd;") described in the C++ Standard,
//  14.5.3, not supported.

//  BOOST_NO_OPERATORS_IN_NAMESPACE: Compiler requires inherited operator
//  friend functions to be defined at namespace scope, then using'ed to boost.
//  Probably GCC specific.  See boost/operators.hpp for example.

//  BOOST_NO_POINTER_TO_MEMBER_CONST: The compiler does not correctly handle
//  pointers to const member functions, preventing use of these in overloaded 
//  function templates.  See boost/functional.hpp for example.

//  BOOST_NO_PRIVATE_IN_AGGREGATE: The compiler misreads 8.5.1, treating classes
//  as non-aggregate if they contain private or protected member functions. 

//  BOOST_NO_STD_ITERATOR: The C++ implementation fails to provide the
//  std::iterator class.

//  BOOST_NO_STD_ITERATOR_TRAITS: The compiler does not provide a standard
//  compliant implementation of std::iterator_traits. Note that
//  the compiler may still have a non-standard implementation.

//  BOOST_NO_STDC_NAMESPACE: The contents of C++ standard headers for C library
//  functions (the <c...> headers) have not been placed in namespace std.
//  Because the use of std::size_t is so common, a specific workaround for
//  <cstddef> (and thus std::size_t) is provided in this header (see below).
//  For other <c...> headers, a workaround must be provided in the boost header:
//
//    #include <cstdlib>  // for abs
//    #ifdef BOOST_NO_STDC_NAMESPACE
//      namespace std { using ::abs; }
//    #endif

//  BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION. Class template partial
//  specialization (14.5.4 [temp.class.spec]) not supported.

//  BOOST_NO_USING_TEMPLATE: The compiler will not accept a using declaration
//  that imports a template from the global namespace into a named namespace.
//  Probably Borland specific.

//  BOOST_NO_AUTO_PTR: If the compiler / library supplies non-standard or broken
//  std::auto_ptr.

//  BOOST_WEAK_FUNCTION_TEMPLATE_ORDERING: The compiler does not perform 
//  function template ordering or its function template ordering is incorrect.
//  
//  template<typename T> void f(T); // #1
//  template<typename T, typename U> void f(T (*)(U)); // #2
//  void bar(int);
//  f(&bar); // should choose #2. 

//  BOOST_NO_DEPENDENT_NESTED_DERIVATIONS: The compiler fails to compile
//  a nested class that has a dependent base class:
//  template<typename T>
//  struct foo : public T {  
//    template<typename U>
//    struct bar : public T, public U {};
//  };

//  
//  Compiler Control or Information Macros  ----------------------------------//
//
//  Compilers often supply features outside of the C++ Standard which need to be
//  controlled or detected. As usual, reasonable default behavior should occur
//  if any of these macros are not defined.

//  BOOST_DECL:  Certain compilers for Microsoft operating systems require
//  non-standard class and function decoration if dynamic load library linking
//  is desired.  BOOST_DECL supplies that decoration.  Boost does not require
//  use of BOOST_DECL - it is non-standard and to be avoided if practical to do
//  so. Even compilers requiring it for DLL's only require it in certain cases.
//
//    BOOST_DECL_EXPORTS:  User defined, usually via command line or IDE,
//    it causes BOOST_DECL to be defined as __declspec(dllexport).
//
//    BOOST_DECL_IMPORTS:  User defined, usually via command line or IDE,
//    it causes BOOST_DECL to be defined as __declspec(dllimport).
//
//    If neither BOOST_DECL_EXPORTS nor BOOST_DECL_IMPORTS is defined, or if
//    the compiler does not require __declspec() decoration, BOOST_DECL is
//    defined as a null string.

//  BOOST_MSVC6_MEMBER_TEMPLATES:  Microsoft Visual C++ 6.0 has enough member
//  template idiosyncrasies (being polite) that BOOST_NO_MEMBER_TEMPLATES is
//  defined for this compiler. BOOST_MSVC6_MEMBER_TEMPLATES is defined to allow
//  compiler specific workarounds.

//  BOOST_MSVC: defined as _MSC_VER for the Microsoft compiler only. In general,
//  boost headers should test for a specific conformance flag macro (for
//  example, BOOST_NO_MEMBER_TEMPLATE_FRIENDS) rather than a specific compiler.
//  VC++ is a special case, however, since many libraries try to support it yet
//  it has so many conformance issues that sometimes it is just easier to test
//  for it directly. On the other hand, the obvious way to do this doesn't work,
//  as many non-Microsoft compilers define _MSC_VER.  Thus BOOST_MSVC.

//  BOOST_MSVC_STD_ITERATOR: Microsoft's broken version of std::iterator
//  is being used. 

//  BOOST_SYSTEM_HAS_STDINT_H: There are no 1998 C++ Standard headers <stdint.h> 
//  or <cstdint>, although the 1999 C Standard does include <stdint.h>. 
//  If <stdint.h> is present, <boost/stdint.h> can make good use of it,
//  so a flag is supplied (signalling presence; thus the default is not
//  present, conforming to the current C++ standard).

//  BOOST_NO_SLIST: The C++ implementation does not provide the slist class.

//  BOOST_NO_STRINGSTREAM: The C++ implementation does not provide the <sstream> header.

//  BOOST_NO_HASH: The C++ implementation does not provide the hash_set
//  or hash_map classes.

//  BOOST_STD_EXTENSION_NAMESPACE: The name of the namespace in which the slist,
//  hash_set and/or hash_map templates are defined in this implementation (if any).

//  BOOST_NO_TEMPLATED_ITERATOR_CONSTRUCTORS: The standard library does not provide
//  templated iterator constructors for its containers.

//  BOOST_NO_LIMITS: The C++ implementation does not provide the <limits> header.

//  BOOST_NO_INTRINSIC_WCHAR_T: The C++ implementation does not provide wchar_t,
//  or it is really a synonym for another integral type. Use this symbol to
//  decide whether it is appropriate to explicitly specialize a template on
//  wchar_t if there is already a specialization for other integer types.

//  BOOST_NO_STD_ALLOCATOR: The C++ standard library does not provide
//  a standards conforming std::allocator.

//  BOOST_NO_STD_MIN_MAX: The C++ standard library does not provide
//  the min() and max() template functions that should be in <algorithm>.
