// typedef <implementation-defined> boost::detail::atomic_count;
//
// atomic_count a(n);
//
// (n is convertible to long)
//
// Effects: Constructs an atomic_count with an initial value of n
//
// a;
//
// Returns: (long) the current value of a
//
// ++a;
//
// Effects: Atomically increments the value of a
// Returns: nothing
//
// --a;
//
// Effects: Atomically decrements the value of a
// Returns: (long) zero if the new value of a is zero,
// unspecified non-zero value otherwise (usually the new value)
//
// Important note: when --a returns zero, it must act as a
// read memory barrier (RMB); i.e. the calling thread must
// have a synchronized view of the memory
//
// On Intel IA-32 (x86) memory is always synchronized, so this
// is not a problem.
//
// On many architectures the atomic instructions already act as
// a memory barrier.
//
// This property is necessary for proper reference counting, since
// a thread can update the contents of a shared object, then
// release its reference, and another thread may immediately
// release the last reference causing object destruction.
//
// The destructor needs to have a synchronized view of the
// object to perform proper cleanup.
//
// Original example by Alexander Terekhov:
//
// Given:
//
// - a mutable shared object OBJ;
// - two threads THREAD1 and THREAD2 each holding
// a private smart_ptr object pointing to that OBJ.
//
// t1: THREAD1 updates OBJ (thread-safe via some synchronization)
// and a few cycles later (after "unlock") destroys smart_ptr;
//
// t2: THREAD2 destroys smart_ptr WITHOUT doing any synchronization
// with respect to shared mutable object OBJ; OBJ destructors
// are called driven by smart_ptr interface...

// Revision History
// 04 Mar 2001 - More attempted fixes for Intel C++ (David Abrahams)
// 03 Mar 2001 - Put all implementation into namespace
// boost::detail::iterator_traits_. Some progress made on fixes
// for Intel compiler. (David Abrahams)
// 02 Mar 2001 - Changed BOOST_MSVC to BOOST_MSVC_STD_ITERATOR in a few
// places. (Jeremy Siek)
// 19 Feb 2001 - Improved workarounds for stock MSVC6; use yes_type and
// no_type from type_traits.hpp; stopped trying to remove_cv
// before detecting is_pointer, in honor of the new type_traits
// semantics. (David Abrahams)
// 13 Feb 2001 - Make it work with nearly all standard-conforming iterators
// under raw VC6. The one category remaining which will fail is
// that of iterators derived from std::iterator but not
// boost::iterator and which redefine difference_type.
// 11 Feb 2001 - Clean away code which can never be used (David Abrahams)
// 09 Feb 2001 - Always have a definition for each traits member, even if it
// can't be properly deduced. These will be incomplete types in
// some cases (undefined<void>), but it helps suppress MSVC errors
// elsewhere (David Abrahams)
// 07 Feb 2001 - Support for more of the traits members where possible, making
// this useful as a replacement for std::iterator_traits<T> when
// used as a default template parameter.
// 06 Feb 2001 - Removed useless #includes of standard library headers
// (David Abrahams)

// (David Abrahams)
// 10 Feb 2001 - Rolled in supposed Borland fixes from John Maddock, but

// 06 Feb 2001 - Factored if_true out into boost/detail/select_type.hpp
// (David Abrahams)
// 23 Jan 2001 - Fixed logic of difference_type selection, which was

// utf8_codecvt_facet.hpp
// This header defines class utf8_codecvt_facet, derived fro
// std::codecvt<wchar_t, char>, which can be used to convert utf8 data in
// files into wchar_t strings in the application.
//
// The header is NOT STANDALONE, and is not to be included by the USER.
// There are at least two libraries which want to use this functionality, and
// we want to avoid code duplication. It would be possible to create utf8
// library, but:
// - this requires review process first
// - in the case, when linking the a library which uses utf8
// (say 'program_options'), user should also link to the utf8 library.
// This seems inconvenient, and asking a user to link to an unrevieved
// library is strange.
// Until the above points are fixed, a library which wants to use utf8 must:
// - include this header from one of it's headers or sources
// - include the corresponding .cpp file from one of the sources
// - before including either file, the library must define
// - BOOST_UTF8_BEGIN_NAMESPACE to the namespace declaration that must be used
// - BOOST_UTF8_END_NAMESPACE to the code to close the previous namespace
// - declaration.
// - BOOST_UTF8_DECL -- to the code which must be used for all 'exportable'
// symbols.
//
// For example, program_options library might contain:
// #define BOOST_UTF8_BEGIN_NAMESPACE <backslash character>
// namespace boost { namespace program_options {
// #define BOOST_UTF8_END_NAMESPACE }}
// #define BOOST_UTF8_DECL BOOST_PROGRAM_OPTIONS_DECL
// #include "../../detail/utf8/utf8_codecvt.cpp"
//
// Essentially, each library will have its own copy of utf8 code, in
// different namespaces.
// Note:(Robert Ramey). I have made the following alterations in the original
// code.
// a) Rendered utf8_codecvt<wchar_t, char> with using templates
// b) Move longer functions outside class definition to prevent inlining
// and make code smaller
// c) added on a derived class to permit translation to/from current
// locale to utf8
// See http://www.boost.org for updates, documentation, and revision history.
// archives stored as text - note these ar templated on the basic
// stream templates to accommodate wide (and other?) kind of characters
//
// note the fact that on libraries without wide characters, ostream is
// is not a specialization of basic_ostream which in fact is not defined
// in such cases. So we can't use basic_ostream<OStream::char_type> but rather
// use two template parameters
//
// utf8_codecvt_facet
// This is an implementation of a std::codecvt facet for translating
// from UTF-8 externally to UCS-4. Note that this is not tied to
// any specific types in order to allow customization on platforms
// where wchar_t is not big enough.
//
// NOTES: The current implementation jumps through some unpleasant hoops in
// order to deal with signed character types. As a std::codecvt_base::result,
// it is necessary for the ExternType to be convertible to unsigned char.
// I chose not to tie the extern_type explicitly to char. But if any combination
// of types other than <wchar_t,char_t> is used, then std::codecvt must be
// specialized on those types for this to work.

// Usage:
//
// #if BOOST_WORKAROUND(BOOST_MSVC, < 1300)
// // workaround for eVC4 and VC6
// ... // workaround code here
// #endif
//
// When BOOST_STRICT_CONFIG is defined, expands to 0. Otherwise, the

// When used for workarounds that apply to the latest known version

// #if BOOST_WORKAROUND(BOOST_MSVC, BOOST_TESTED_AT(1301))
//
// The version number in this case corresponds to the last version in
// which the workaround was known to have been required. When
// BOOST_DETECT_OUTDATED_WORKAROUNDS is not the defined, the macro
// BOOST_TESTED_AT(x) expands to "!= 0", which effectively activates
// the workaround for any version of the compiler. When
// BOOST_DETECT_OUTDATED_WORKAROUNDS is defined, a compiler warning or
// error will be issued if the compiler version exceeds the argument
// to BOOST_TESTED_AT(). This can be used to locate workarounds which
// may be obsoleted by newer versions.
