I would too expect that these changes are not a good idea. In normal<br>
case libbsd builds without any trouble.<br>
<br>
Can you give some more information about the exact versions you use:<br>
<br>
- Which commit of libbsd are you trying to build?<br>
- Which rtems commit do you use?<br>
- Which tool version do you use? If RSB: Which commit?<br>
- What BSP do you use?<br>
<br>
Best regards<br>
