     The ISO standard defines the following phrase:
   </p><div class="blockquote"><blockquote class="blockquote"><div class="variablelist"><dl><dt><span class="term">
	 <code class="code">[1.3.5] implementation-defined behavior</code>
       </span></dt><dd><p>
	 Behavior, for a well-formed program construct and correct data, that
         depends on the implementation <span class="emphasis"><em>and that each implementation
         shall document</em></span>.
	 </p></dd></dl></div></blockquote></div><p>
     We do so here, for the C++ library only.  Behavior of the
     compiler, linker, runtime loader, and other elements of "the
     implementation" are documented elsewhere.  Everything listed
     in Annex B, Implementation Qualities, are also part of the
     compiler, not the library.
   </p><p>
     For each entry, we give the section number of the standard, when
     applicable.  This list is probably incomplet and inkorrekt.
   </p><p>
     <span class="emphasis"><em>[1.9]/11 #3</em></span> If <code class="code">isatty(3)</code> is true, then
      interactive stream support is implied.
   </p><p>
     <span class="emphasis"><em>[17.4.4.5]</em></span> Non-reentrant functions are probably best
      discussed in the various sections on multithreading (see above).
   </p><p><span class="emphasis"><em>[18.1]/4</em></span> The type of <code class="code">NULL</code> is described
      <a class="link" href="bk01pt02ch04s03.html" title="NULL">here</a>.
   </p><p><span class="emphasis"><em>[18.3]/8</em></span> Even though it's listed in the library
      sections, libstdc++ has zero control over what the cleanup code hands
      back to the runtime loader.  Talk to the compiler people.  :-)
   </p><p><span class="emphasis"><em>[18.4.2.1]/5</em></span> (bad_alloc),
      <span class="emphasis"><em>[18.5.2]/5</em></span> (bad_cast),
      <span class="emphasis"><em>[18.5.3]/5</em></span> (bad_typeid),
      <span class="emphasis"><em>[18.6.1]/8</em></span> (exception),
      <span class="emphasis"><em>[18.6.2.1]/5</em></span> (bad_exception):  The <code class="code">what()</code>
      member function of class <code class="code">std::exception</code>, and these other
      classes publicly derived from it, simply returns the name of the
      class.  But they are the <span class="emphasis"><em>mangled</em></span> names; you will need to call
      <code class="code">c++filt</code> and pass the names as command-line parameters to
      demangle them, or call a
      <a class="link" href="ext_demangling.html" title="Chapter 40. Demangling">runtime demangler function</a>.
      (The classes in <code class="code">&lt;stdexcept&gt;</code> have constructors which
      require an argument to use later for <code class="code">what()</code> calls, so the
      problem of <code class="code">what()</code>'s value does not arise in most
      user-defined exceptions.)
   </p><p><span class="emphasis"><em>[18.5.1]/7</em></span> The return value of
      <code class="code">std::type_info::name()</code> is the mangled type name (see the
      previous entry for more).
   </p><p><span class="emphasis"><em>[20.1.5]/5</em></span> <span class="emphasis"><em>"Implementors are encouraged to
      supply libraries that can accept allocators that encapsulate more
      general memory models and that support non-equal instances.  In such
      implementations, any requirements imposed on allocators by containers
      beyond those requirements that appear in Table 32, and the semantics
      of containers and algorithms when allocator instances compare
      non-equal, are implementation-defined."</em></span>  As yet we don't
      have any allocators which compare non-equal, so we can't describe how
      they behave.

      Nope, these types are called implementation-defined because you
      shouldn't be taking advantage of their underlying types.  Listing them
      here would defeat the purpose.  :-)
   </p><p><span class="emphasis"><em>[21.1.3.1]/5</em></span> I don't really know about
      the mbstate_t stuff... see
      the <a class="link" href="codecvt.html" title="codecvt">chapter 22
      notes</a> for what does exist.
   </p><p><span class="emphasis"><em>[22.*]</em></span> Anything and everything we have on locale

   </p><p><span class="emphasis"><em>[26.2.8]/9</em></span> I have no idea what
      <code class="code">complex&lt;T&gt;</code>'s pow(0,0) returns.
   </p><p><span class="emphasis"><em>[27.4.2.4]/2</em></span> Calling
      <code class="code">std::ios_base::sync_with_stdio</code> after I/O has already been
      performed on the standard stream objects will
      flush the buffers, and 
      destroy and recreate the underlying buffer instances.  Whether or not
      the previously-written I/O is destroyed in this process depends mostly
      on the --enable-libio choice:  for stdio, if the written data is
      already in the stdio buffer, the data may be completely safe!
   </p><p><span class="emphasis"><em>[27.6.1.1.2]</em></span>,
      <span class="emphasis"><em>[27.6.2.3]</em></span> The I/O sentry ctor and dtor can perform
      additional work than the minimum required.  We are not currently taking
      advantage of this yet.

      <span class="emphasis"><em>[27.8.1.4]/10</em></span>
      The effects of <code class="code">pubsetbuf/setbuf</code> are described

   </p><p><span class="emphasis"><em>[27.8.1.4]/16</em></span> Calling <code class="code">fstream::sync</code> when
