+ 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="ulink" href="http://www.open-std.org/jtc1/sc22/wg21/" target="_top">ISO C++
+ Committee homepage</a>, linked to on the
+ <a class="ulink" 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="ulink" href="lwg-active.html#DR" target="_top">DR</a> status.
