<P>[Moved to DR at the May, 2015 meeting.]</P>



<P>The resolution of <A HREF="1514.html">issue 1514</A> was intended
to apply whenever <TT>enum</TT> <I>identifier</I> appears; however, the
fact that the disambiguation rule appears in the description of the
<I>enum-specifier</I> makes it unclear that it is intended to apply in
other contexts such as:</P>

<PRE>
  enum E { e1 };
  void f() {
    false ? new enum E : int();
  }
</PRE>

<P><B>Proposed resolution (April, 2015):</B></P>

<P>Change 9.8.1 [<A href="https://wg21.link/dcl.enum#1">dcl.enum</A>] paragraph 1 as follows:</P>

<BLOCKQUOTE>

A <TT>:</TT> following &#8220;<TT>enum</TT> <I>identifier</I>&#8221;
<INS>within the <I>decl-specifier-seq</I> of
a <I>member-declaration</I></INS> is parsed as part of
an <I>enum-base</I>. [<I>Note:</I> This resolves a potential
ambiguity between the declaration of an enumeration with
an <I>enum-base</I> and the declaration of an unnamed bit-field
of enumeration type...
