| 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><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. |
