+// headers will include all the necessary bits. If not defined, the
+// implementation optimizes the headers for the most commonly-used

+// In those parts of the standard C++ library that use a mutex instead
+// of a spin-lock, we now unconditionally use GCC's gthr.h mutex
+// abstraction layer. All support to directly map to various
+// threading models has been removed. Note: gthr.h may well map to
+// gthr-single.h which is a correct way to express no threads support
+// in gcc. Support for the undocumented _NOTHREADS has been removed.

+// snapshots). See libstdc++-v3/docs/html/17_intro/howto.html for
+// details on why you don't want to override this setting. Ensure
+// that threads are properly configured on your platform before
+// assigning blame to the STL container-memory allocator. After doing
+// so, please report any possible issues to libstdc++@gcc.gnu.org .
+// Do not blindly #define __USE_MALLOC here or on the command line.
+
+// The remainder of the prewritten config is mostly automatic; all the
+// user hooks are listed above.

+// can be used in control structures and the optimizer hopefully will do
+// the obvious thing.
+//
+// Why integral expressions, and not functions nor types?
+// Firstly, these compile-time entities are used as template-arguments
+// so function return values won't work: We need compile-time entities.
+// We're left with types and constant integral expressions.
+// Secondly, from the point of view of ease of use, type-based compile-time
+// information is -not- *that* convenient. On has to write lots of
+// overloaded functions and to hope that the compiler will select the right
+// one. As a net effect, the overall structure isn't very clear at first
+// glance.
+// Thirdly, partial ordering and overload resolution (of function templates)
+// is highly costly in terms of compiler-resource. It is a Good Thing to
+// keep these resource consumption as least as possible.

+ * @defgroup Allocators Memory Allocators
+ * @if maint
+ * stl_alloc.h implements some node allocators. These are NOT the same as
+ * allocators in the C++ standard, nor in the original H-P STL. They do not
+ * encapsulate different pointer types; we assume that there is only one
+ * pointer type. The C++ standard allocators are intended to allocate
+ * individual objects, not pools or arenas.
+ *
+ * In this file allocators are of two different styles: "standard" and
+ * "SGI" (quotes included). "Standard" allocators conform to 20.4. "SGI"
+ * allocators differ in AT LEAST the following ways (add to this list as you
+ * discover them):
+ *
+ * - "Standard" allocate() takes two parameters (n_count,hint=0) but "SGI"
+ * allocate() takes one paramter (n_size).
+ * - Likewise, "standard" deallocate()'s argument is a count, but in "SGI"
+ * is a byte size.
+ * - max_size(), construct(), and destroy() are missing in "SGI" allocators.
+ * - reallocate(p,oldsz,newsz) is added in "SGI", and behaves as
+ * if p=realloc(p,newsz).
+ *
+ * "SGI" allocators may be wrapped in __allocator to convert the interface
+ * into a "standard" one.
+ * @endif
+ *
+ * The canonical description of these classes is in docs/html/ext/howto.html

+ * @if maint
+ * Another allocator adaptor: _Alloc_traits. This serves two purposes.
+ * First, make it possible to write containers that can use either "SGI"
+ * style allocators or "standard" allocators. Second, provide a mechanism
+ * so that containers can query whether or not the allocator has distinct
+ * instances. If not, the container can avoid wasting a word of memory to
+ * store an empty object. For examples of use, see stl_vector.h, etc, or
+ * any of the other classes derived from this one.
+ *
+ * This adaptor uses partial specialization. The general case of
+ * _Alloc_traits<_Tp, _Alloc> assumes that _Alloc is a
+ * standard-conforming allocator, possibly with non-equal instances and
+ * non-static members. (It still behaves correctly even if _Alloc has
+ * static member and if all instances are equal. Refinements affect
+ * performance, not correctness.)
+ *
+ * There are always two members: allocator_type, which is a standard-
+ * conforming allocator type for allocating objects of type _Tp, and
+ * _S_instanceless, a static const member of type bool. If
+ * _S_instanceless is true, this means that there is no difference
+ * between any two instances of type allocator_type. Furthermore, if
+ * _S_instanceless is true, then _Alloc_traits has one additional
+ * member: _Alloc_type. This type encapsulates allocation and
+ * deallocation of objects of type _Tp through a static interface; it
+ * has two member functions, whose signatures are
+ *
+ * - static _Tp* allocate(size_t)
+ * - static void deallocate(_Tp*, size_t)
+ *
+ * The size_t parameters are "standard" style (see top of stl_alloc.h) in
+ * that they take counts, not sizes.

+ *
+ * Placeholder: see http://www.sgi.com/tech/stl/Deque.html for now.
+ *
+ * In previous HP/SGI versions of deque, there was an extra template parameter
+ * so users could control the node size. This extension turned out to violate
+ * the C++ standard (it can be detected using template template parameters),
+ * and it was removed.
+ *
+ * @if maint
+ * Here's how a deque<Tp> manages memory. Each deque has 4 members:
+ *
+ * - Tp** _M_map
+ * - size_t _M_map_size
+ * - iterator _M_start, _M_finish
+ *
+ * map_size is at least 8. %map is an array of map_size pointers-to-"nodes".
+ * (The name has nothing to do with the std::map class.)
+ *
+ * A "node" has no specific type name as such, but it is referred to as
+ * "node" in this file. It is a simple array-of-Tp. If Tp is very large,
+ * there will be one Tp element per node (i.e., an "array" of one).
+ * For non-huge Tp's, node size is inversely related to Tp size: the
+ * larger the Tp, the fewer Tp's will fit in a node. The goal here is to
+ * keep the total size of a node relatively small and constant over different
+ * Tp's, to improve allocator efficiency.
+ *
+ * **** As I write this, the nodes are /not/ allocated using the high-speed
+ * memory pool. There are 20 hours left in the year; perhaps I can fix
+ * this before 2002.
+ *
+ * Not every pointer in the %map array will point to a node. If the initial
+ * number of elements in the deque is small, the /middle/ %map pointers will
+ * be valid, and the ones at the edges will be unused. This same situation
+ * will arise as the %map grows: available %map pointers, if any, will be on
+ * the ends. As new nodes are created, only a subset of the %map's pointers
+ * need to be copied "outward".
+ *
+ * Class invariants:
+ * - For any nonsingular iterator i:
+ * - i.node points to a member of the %map array. (Yes, you read that
+ * correctly: i.node does not actually point to a node.) The member of
+ * the %map array is what actually points to the node.
+ * - i.first == *(i.node) (This points to the node (first Tp element).)
+ * - i.last == i.first + node_size
+ * - i.cur is a pointer in the range [i.first, i.last). NOTE:
+ * the implication of this is that i.cur is always a dereferenceable
+ * pointer, even if i is a past-the-end iterator.
+ * - Start and Finish are always nonsingular iterators. NOTE: this means that
+ * an empty deque must have one node, a deque with <N elements (where N is
+ * the node buffer size) must have one node, a deque with N through (2N-1)
+ * elements must have two nodes, etc.
+ * - For every node other than start.node and finish.node, every element in the
+ * node is an initialized object. If start.node == finish.node, then
+ * [start.cur, finish.cur) are initialized objects, and the elements outside
+ * that range are uninitialized storage. Otherwise, [start.cur, start.last)
+ * and [finish.first, finish.cur) are initialized objects, and [start.first,
+ * start.cur) and [finish.cur, finish.last) are uninitialized storage.
+ * - [%map, %map + map_size) is a valid, non-empty range.
+ * - [start.node, finish.node] is a valid range contained within
+ * [%map, %map + map_size).
+ * - A pointer in the range [%map, %map + map_size) points to an allocated node
+ * if and only if the pointer is in the range [start.node, finish.node].
+ *
+ * Here's the magic: nothing in deque is "aware" of the discontiguous storage!
+ *
+ * The memory setup and layout occurs in the parent, _Base, and the iterator
+ * class is entirely responsible for "leaping" from one node to the next. All
+ * the implementation routines for deque itself work only through the start
+ * and finish iterators. This keeps the routines simple and sane, and we can
+ * use other standard algorithms as well.

+/** @defgroup s20_3_1_base Functor Base Classes
+ * Function objects, or @e functors, are objects with an @c operator()
+ * defined and accessible. They can be passed as arguments to algorithm
+ * templates and used in place of a function pointer. Not only is the
+ * resulting expressiveness of the library increased, but the generated
+ * code can be more efficient than what you might write by hand. When we
+ * refer to "functors," then, generally we include function pointers in
+ * the description as well.
+ *
+ * Often, functors are only created as temporaries passed to algorithm
+ * calls, rather than being created as named variables.
+ *
+ * Two examples taken from the standard itself follow. To perform a
+ * by-element addition of two vectors @c a and @c b containing @c double,
+ * and put the result in @c a, use
+ * \code
+ * transform (a.begin(), a.end(), b.begin(), a.begin(), plus<double>());
+ * \endcode
+ * To negate every element in @c a, use
+ * \code
+ * transform(a.begin(), a.end(), a.begin(), negate<double>());
+ * \endcode
+ * The addition and negation functions will be inlined directly.
+ *
+ * The standard functiors are derived from structs named @c unary_function
+ * and @c binary_function. These two classes contain nothing but typedefs,
+ * to aid in generic (template) programming. If you write your own
+ * functors, you might consider doing the same.

+/** @defgroup s20_3_8_memadaptors Adaptors for pointers to members
+ * There are a total of 16 = 2^4 function objects in this family.
+ * (1) Member functions taking no arguments vs member functions taking
+ * one argument.
+ * (2) Call through pointer vs call through reference.
+ * (3) Member function with void return type vs member function with
+ * non-void return type.
+ * (4) Const vs non-const member function.
+ *
+ * Note that choice (3) is nothing more than a workaround: according
+ * to the draft, compilers should handle void and non-void the same way.
+ * This feature is not yet widely implemented, though. You can only use
+ * member functions returning void if your compiler supports partial
+ * specialization.
+ *
+ * All of this complexity is in the function objects themselves. You can
+ * ignore it by using the helper function mem_fun and mem_fun_ref,
+ * which create whichever type of adaptor is appropriate.
+ *

+Red-black tree class, designed for use in implementing STL
+associative containers (set, multiset, map, and multimap). The
+insertion and deletion algorithms are based on those in Cormen,
+Leiserson, and Rivest, Introduction to Algorithms (MIT Press, 1990),
+except that
+
+(1) the header cell is maintained with links not only to the root
+but also to the leftmost node of the tree, to enable constant time
+begin(), and to the rightmost node of the tree, to enable linear time
+performance when used with the generic set algorithms (set_union,
+etc.);
+
+(2) when a node being deleted has two children its successor node is
+relinked into its place, rather than copied, so that the only
+iterators invalidated are those referring to the deleted node.

+This header file provides a framework for allowing compile time dispatch
+based on type attributes. This is useful when writing template code.
+For example, when making a copy of an array of an unknown type, it helps
+to know if the type has a trivial copy constructor or not, to help decide
+if a memcpy can be used.
+
+The class template __type_traits provides a series of typedefs each of
+which is either __true_type or __false_type. The argument to
+__type_traits can be any type. The typedefs within this template will
+attain their correct values by one of these means:
+ 1. The general instantiation contain conservative values which work
+ for all types.
+ 2. Specializations may be declared to make distinctions between types.
+ 3. Some compilers (such as the Silicon Graphics N32 and N64 compilers)
+ will automatically provide the appropriate specializations for all
+ types.
+
+EXAMPLE:
+
+//Copy an array of elements which have non-trivial copy constructors
+template <class _Tp> void
+ copy(_Tp* __source,_Tp* __destination,int __n,__false_type);
+//Copy an array of elements which have trivial copy constructors. Use memcpy.
+template <class _Tp> void
+ copy(_Tp* __source,_Tp* __destination,int __n,__true_type);
+
+//Copy an array of any type by using the most efficient copy mechanism
+template <class _Tp> inline void copy(_Tp* __source,_Tp* __destination,int __n) {
+ copy(__source,__destination,__n,
+ typename __type_traits<_Tp>::has_trivial_copy_constructor());
+}
+*/
+
+struct __true_type {};
+struct __false_type {};
+
+template <class _Tp>
+struct __type_traits {
+ typedef __true_type this_dummy_member_must_be_first;
+ /* Do not remove this member. It informs a compiler which
+ automatically specializes __type_traits that this
+ __type_traits template is special. It just makes sure that
+ things work if an implementation is using a template
+ called __type_traits for something unrelated. */
+
+ /* The following restrictions should be observed for the sake of
+ compilers which automatically produce type specific specializations
+ of this class:
+ - You may reorder the members below if you wish
+ - You may remove any of the members below if you wish
+ - You must not rename members without making the corresponding

+ * @brief The %bitset class represents a @e fixed-size sequence of bits.
+ *
+ * @ingroup Containers
+ *
+ * (Note that %bitset does @e not meet the formal requirements of a
+ * <a href="tables.html#65">container</a>. Mainly, it lacks iterators.)
+ *
+ * The template argument, @a _Nb, may be any nonzero number of type
+ * size_t.
+ *
+ * A %bitset of size N has N % (sizeof(unsigned long) * CHAR_BIT) unused
+ * bits. (They are the high-order bits in the highest word.) It is
+ * a class invariant that those unused bits are always zero.
+ *
+ * If you think of %bitset as "a simple array of bits," be aware that
+ * your mental picture is reversed: a %bitset behaves the same way as
+ * bits in integers do, with the bit at index 0 in the "least significant
+ * / right-hand" position, and the bit at index N-1 in the "most
+ * significant / left-hand" position. Thus, unlike other containers, a
+ * %bitset's index "counts from right to left," to put it very loosely.
+ *
+ * This behavior is preserved when translating to and from strings. For
+ * example, the first line of the following program probably prints
+ * "b('a') is 0001100001" on a modern ASCII system.
+ *
+ * @code
+ * #include <bitset>
+ * #include <iostream>
+ * #include <sstream>
+ *
+ * using namespace std;
+ *
+ * int main()
+ * {
+ * long a = 'a';
+ * bitset<10> b(a);
+ *
+ * cout << "b('a') is " << b << endl;
+ *
+ * ostringstream s;
+ * s << b;
+ * string str = s.str();
+ * cout << "index 3 in the string is " << str[3] << " but\n"
+ * << "index 3 in the bitset is " << b[3] << endl;
+ * }
+ * @endcode
+ *
+ * Also see http://gcc.gnu.org/onlinedocs/libstdc++/ext/sgiexts.html#ch23
+ *
+ * @if maint
+ * Most of the actual code isn't contained in %bitset<> itself, but in the
+ * base class _Base_bitset. The base class works with whole words, not with
+ * individual bits. This allows us to specialize _Base_bitset for the
+ * important special case where the %bitset is only a single word.
+ *
+ * Extra confusion can result due to the fact that the storage for
+ * _Base_bitset @e is a regular array, and is indexed as such. This is
+ * carefully encapsulated.
