      <para>
	Everybody's got issues.  Even the C++ Standard Library.
      </para>
      <para>
	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.
      </para>
      <para>
	Here are the issues which have resulted in code changes to the library.
	The links are to the specific defect reports from a <emphasis>partial
	copy</emphasis> of the Issues List.  You can read the full version online
	at the <ulink url="http://www.open-std.org/jtc1/sc22/wg21/">ISO C++
	Committee homepage</ulink>, linked to on the
	<ulink url="http://gcc.gnu.org/readings.html">GCC &quot;Readings&quot;
	page</ulink>.  If
	you spend a lot of time reading the issues, we recommend downloading
	the ZIP file and reading them locally.
      </para>
      <para>
	(NB: <emphasis>partial copy</emphasis> 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.)
      </para>
      <para>
	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
	<constant>_GLIBCXX_RESOLVE_LIB_DEFECTS</constant> for examples
	of style.  Note that we usually do not make changes to the
	code until an issue has reached <ulink url="lwg-active.html#DR">DR</ulink> status.
