C++ 11 standard library implementation with extra features using C++98 only and POSIX threads. Minimum ugly preprocessor macro and no configuration files. The library itself is built on top of C++ standard library distributed with your compiler and just extends it with C++11 features.

Usage examples on Wiki

Supported platforms

Windows (from XP to 10)
Unix (any with glibc and pthread)
MacOS (any)
QNX 6.x.x
QNX 4 (partly)

Q: Why not Boost?

Because I can.
Because I need something without such overhead and ugliness (ugliness and beauty actually, I am really amazed by how Boost handles some features of C++).
Because I want all of basic little helpful classes and tricks (as countof f.e.) be in one place with power of C++ 11 threads handling and template-programming.

Language core

nullptr and stdex::nullptr_t
static_assert or STATIC_ASSERT macro
stdex_char16_t and stdex_char32_t (as equivalent to char16_t, char32_t)
stdex_noexcept (as partial equivalent to noexcept)
stdex_assert macro (as equivalent to cassert macro)
move semantic is in progress

Not all features of C++ 11 can be implemented without compiler support so I have no plans to include such features in the library.

The library is portable for any compiler that supports C++98 but as we all know there are lots of different implementations of std library in even major compilers so this library is tested with:

Borland C++ Builder 6.0 Updt4;
qcc (just a wrapper over gcc in QNX)
g++ 3.4, 4.4.2, 4.4, 4.6;
g++ 4.8, 4.9, 5.0 with c++98 option;
clang 3.5, 5.0 with c++98 option;
clang-900.0.37 with c++98 option (Mac OS);
Visual Studio 2008, 2010, 2013, 2015, 2017;

...and that's it. If you use other compilers and decide to include this library in your project there is no guarantee that it will compile without errors. In case you will be able to fix the errors without breaking existing code for already supported compilers I would really appreciate your pull requests.
