Here we will make an attempt at describing the non-Standard
extensions to the library. Some of these are from older versions of
standard library components, namely SGI's STL, and some of these are
GNU's.
</p><p><span class="emphasis"><em>Before</em></span> you leap in and use any of these
extensions, be aware of two things:
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p>
Non-Standard means exactly that.
</p><p>
The behavior, and the very
existence, of these extensions may change with little or no
warning. (Ideally, the really good ones will appear in the next
revision of C++.) Also, other platforms, other compilers, other
versions of g++ or libstdc++ may not recognize these names, or
treat them differently, or...
</p></li><li class="listitem"><p>
You should know how to access these headers properly.
