+@section C++ Class Names
+
+In C++, a class name which is declared with @code{class}, @code{struct},
+or @code{union}, is not only a tag, as in C, but also a type name.  Thus
+there should be stabs with both @samp{t} and @samp{T} symbol descriptors
+(@pxref{Typedefs}).
+
+To save space, there is a special abbreviation for this case.  If the
+@samp{T} symbol descriptor is followed by @samp{t}, then the stab
+defines both a type name and a tag.
+
+For example, the C++ code
+
+@example
+struct foo @{int x;@};
+@end example
+
+can be represented as either
+
+@example
+.stabs "foo:T19=s4x:1,0,32;;",128,0,0,0       # @r{128 is N_LSYM}

-@c FIXME:  What does "part of the string" mean?
 Protections for class member data are signified by two characters
 embedded in the stab defining the class type.  These characters are
-located after the name: part of the string.  @samp{/0} means private,
+located after the @samp{name:} part of the string.  @samp{/0} means private,
 @samp{/1} means protected, and @samp{/2} means public.  If these
 characters are omited this means that the member is public.  The
