In the following example, even though both <code>n</code> and <code>delta</code>

require that both parameters be promoted to the next bigger <code>signed</code>
integer type (in this case <code>signed int</code>) before being added together.
integer type (in this case <code>signed int</code>) before being added together.
As a result, the entire expression is evaluated using <code>signed</code> values
and its value is therefore undefined. (Note, however, that the addition cannot
overflow since we are adding two "small" <code>unsigned short</code> values.)
