54e2fff2e1 Saleem Abdulrasool: If errno is defined as volatile int, the qualifier differences can cause 
template typename deductions on swap<> (used in string.cpp).  Use
decltype(errno) to replicate the type and qualifier information for holding the
errno value.  Because errno is expected to be assignable, there is no need to
use typename std::remove_const<decltype(errno)>::type to hold the value.

access and ambiguity for a derived-to-base conversion. This passes all

cf115d2cc6 Change sleep_for, sleep_until, and the condition_variable timed wait 
functions to protect against duration and time_point overflow.  Since
we're about to wait anyway, we can afford to spend a few more cycles on
this checking.  I purposefully did not treat the timed try_locks with
overflow checking.  This fixes
http://llvm.org/bugs/show_bug.cgi?id=13721 .  I'm unsure if the standard
needs clarification in this area, or if this is simply QOI.  The
<chrono> facilities were never intended to overflow check, but just to
not overflow if durations stayed within +/- 292 years.

a5160283a4 Michel Morin: My previous fix for C++03 was incomplete. 
It does not consider user-defined conversions that convert an rvalue
into an lvalue and works incorrectly for types with such a conversion
operator.
For example, 

    struct foo
    {
        operator int&();
    };

 returns false_type.

d305d3c1a2 Hyeon-Bin Jeong: 1. sync() should reset it’s external buffer pointers. 
Remaining characters should be discarded once sync() called. If don’t, garbage
characters can be inserted to the front of external buffer in underflow().
Because underflow() copies remaining characters in external buffer to it’s
front. This results wrong characters insertion when seekpos() or seekoff() is
called.

this line should be inserted in sync() just before return:
__extbufnext_ = __extbufend_ = __extbuf_;

2. sync() should use length() rather than out() to calculate offset.
Reversing iterators and calling out() to calculate offset from behind is
working fine in stateless character encoding. However, in stateful encoding,
escape sequences could differ in length. As a result, out() could return wrong
length. 

For example, if we have internal buffer converted from this external sequence:
(capital letters mean escape sequence)
… a a a a B b b b b

out() produces this sequence. 
b b b b A a a a a

Because out() inserts escape sequence A rather than B, result sequence doesn't
match to external sequence. A and B could have different lengths, result offset
could be wrong value too.

length() method in codecvt is right for calculating offset, but it counts
offset from the beginning of buffer. So it requires another state member
variable to hold state before conversion.
