  20    <p>In C++, a class name which is declared with <code>class</code>, <code>struct</code>,
  21 or <code>union</code>, is not only a tag, as in C, but also a type name.  Thus
  22 there should be stabs with both <code>t</code> and <code>T</code> symbol descriptors
  23 (see <a href="Typedefs.html#Typedefs">Typedefs</a>).
  24
  25    <p>To save space, there is a special abbreviation for this case.  If the
  26 <code>T</code> symbol descriptor is followed by <code>t</code>, then the stab
  27 defines both a type name and a tag.
  28
  29    <p>For example, the C++ code
  30
  31 <pre class="example">     struct foo {int x;};
  32      </pre>
  33
  34    <p>can be represented as either
  35
  36 <pre class="example">     .stabs "foo:T19=s4x:1,0,32;;",128,0,0,0       # 128 is N_LSYM
  37      .stabs "foo:t19",128,0,0,0
  38      </pre>
  39
  40    <p>or
  41
  42 <pre class="example">     .stabs "foo:Tt19=s4x:1,0,32;;",128,0,0,0
  43      </pre>
