- <h2>C language issues</h2>

- <h3>Boolean type promotion changes</h3>
- 
- <p>
- The C compiler no longer promotes boolean values in arithmetic
- statements to integer values. Configure-related code that checks for
- C99's &lt;stdbool.h&gt; may be impacted. If the following line is
- newly present in configure logs, then &lt;stdbool.h&gt; support is
- incorrectly configured.
- </p>
- 
- <pre>
- checking for stdbool.h that conforms to C99... no
