| Everybody's got issues. Even the C++ Standard Library. |
| </p><p> |
| The Library Working Group, or LWG, is the ISO subcommittee responsible |
| for making changes to the library. They periodically publish an |
| Issues List containing problems and possible solutions. As they reach |
| a consensus on proposed solutions, we often incorporate the solution. |
| </p><p> |
| Here are the issues which have resulted in code changes to the library. |
| The links are to the specific defect reports from a <span class="emphasis"><em>partial |
| copy</em></span> of the Issues List. You can read the full version online |
| at the <a class="link" href="http://www.open-std.org/jtc1/sc22/wg21/" target="_top">ISO C++ |
| Committee homepage</a>, linked to on the |
| <a class="link" href="http://gcc.gnu.org/readings.html" target="_top">GCC "Readings" |
| page</a>. If |
| you spend a lot of time reading the issues, we recommend downloading |
| the ZIP file and reading them locally. |
| </p><p> |
| (NB: <span class="emphasis"><em>partial copy</em></span> means that not all |
| links within the lwg-*.html pages will work. Specifically, |
| links to defect reports that have not been accorded full DR |
| status will probably break. Rather than trying to mirror the |
| entire issues list on our overworked web server, we recommend |
| you go to the LWG homepage instead.) |
| </p><p> |
| If a DR is not listed here, we may simply not have gotten to |
| it yet; feel free to submit a patch. Search the include/bits |
| and src directories for appearances of |
| <code class="constant">_GLIBCXX_RESOLVE_LIB_DEFECTS</code> for examples |
| of style. Note that we usually do not make changes to the |
| code until an issue has reached <a class="link" href="../ext/lwg-active.html#DR" target="_top">DR</a> status. |
