<P>[Voted into the WP at the February, 2012 meeting;
moved to DR at the October, 2012 meeting.]</P>

<P>There is no normative requirement on the ranges of the integral
types, although the footnote in 6.9.2 [<A href="https://wg21.link/basic.fundamental#2">basic.fundamental</A>] paragraph 2
indicates the intent (for <TT>int</TT>, at least)
that they match the values given in the <TT>&lt;climits&gt;</TT>
header.  Should there be an explicit requirement of some sort?</P>

<P>(See also paper N1693.)</P>

<P><B>Proposed resolution (August, 2011):</B></P>

<P>Change 6.9.2 [<A href="https://wg21.link/basic.fundamental#3">basic.fundamental</A>] paragraph 3 as follows:</P>

<BLOCKQUOTE>

...collectively called the <I>extended integer types</I>.  <INS>The
signed and unsigned integral types shall satisfy the constraints given
in ISO C 5.2.4.2.1.</INS>
