8cad46266c I have to revert this recent fix to tuple conversions until clang implements cwg 1170. Without this fix pair and tuple don't convert properly. With it, associative containers get access errors when they shouldn't. cwg 1170 fixes the latter.

f1bf6f9a3a Chris Jefferson found a defect in the C++0x working draft by trying to run libc++ against boost. I've submitted an issue to the LWG, and this commit attempts to implement the proposed resolution of that defect report. I'd point to the issue but it hasn't been put into the LWG list yet. The title of the issue will be: Stage 2 accumulate incompatibilty

0c68ed006d Chris Jefferson spotted a problem with messages_base::catalog while getting libc++ to work on boost. The standard says this type must be an int. But this type is the key returned by the OS facility catopen. On OS X the type returned by catopen is void*, which doesn't fit into an int on 64 bit platforms. Chris suggested using ptrdiff_t instead of void*. It still isn't compliant with the standard, but chances are that this change will fix what is ailing boost. Chris also supplied the algorithm for distinguishing high-order pointers from error conditions. Thanks Chris.

71711a673b Inline namespaces are always available in Clang. Rely on that without 
testing via __has_feature, since __has_feature for C++0x features no
longer evaluates true in C++98/03 mode.

Also, eliminate the redundant using directive. Inline namespaces make
their members visible in the enclosing namespace automatically.

d18302f1bb Teach move_iterator that rvalue references cannot bind to non-function 
lvalues, nor can one take the address of an xvalue, by adding
appropriate static_cast's (in the first case) and a temporary (in the
second case).

175a104028 Remove an (incorrect) compiler workaround in the __mu function. The 
workaround relied on rvalue references binding to non-function

right thing.

a7b2241407 Eliminate the C++0x-only is_convertible testing function that accepts 
a cv-qualifier rvalue reference to the type, e.g.,

  template <class _Tp> char  __test(const volatile typename remove_reference<_Tp>::type&&);

The use of this function signature rather than the more
straightforward one used in C++98/03 mode, e.g.,

  template <class _Tp> char  __test(_Tp);

is broken in two ways:

  1) An rvalue reference cannot bind to lvalues, so is_convertible<X&,
  X&>::value would be false. This breaks two of the unique_ptr tests
  on Clang and GCC >= 4.5. Prior GCC's seem to have allowed rvalue
  references to bind to lvalues, allowing this bug to slip in.

  2) By adding cv-qualifiers to the type we're converting to, we get
  some incorrect "true" results for, e.g., is_convertible<const X&, X&>::value.

7f64810bc8 LWG 1385 [FCD] tuple_cat should be a single variadic signature (http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#1385). This issue is only in Ready status, meaning it is not official, but probably will be this March in Madrid. It was tentatively accepted in Batavia with the previso that Bill and I didn't have any problems implementing it. This is my part of that agreement.

b5452b3db5 After a long break to wait for the atomic spec to settle, this completes the library part of <atomic>. It currently won't even parse as it depends on the existence of the intrinsics specified at http://libcxx.llvm.org/atomic_design_a.html. Everything has been tested using fake intrinsics which have now been removed. As the intrinsics come online, the ATOMIC_* macros will need to be adjusted to reflect which operations are lock-free. These macros will probably need to be #ifdef'd for each supported platform.
