versions of C++ standard library
<p>Hi
What are difference between The GNU C++ Library (libstdc++),  <a href="http://en.wikipedia.org/wiki/C%2B%2B_standard_library">"C++ Standard Library"</a>,  <a href="http://en.wikipedia.org/wiki/Standard_Template_Library.">"Standard Template Library"</a> and "SGI STL". When programming in Linux with compiler GCC and programming in Windos in MSVC (MicroSoft Visual C++), which the standard C++ libraries are using by default?
Thanks!</p>
