<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">If the compiler being used is clang I think this should be required here and not just a warning when you actually try to compile. If the support doesn't exist it's just not going to work and having configure succeed is just putting off the inevitable failure.</pre>

This patch *should* make Asterisk compile under clang. Note that compiling with --enable-dev-mode will cause Asterisk to fail to compile under clang, as it detects a number of warnings that aren't fixed under this patch.</pre>
