asterisk users - Jul 2014 - Use of undeclared identifier 'pvt' in asterisk-12.4.0

I downloaded asterisk-12.4.0 (asterisk-12-current.tar.gz, dated
10-JUL_2014) from
http://downloads.asterisk.org/pub/telephony/asterisk/.

The packaged configured OK. However, I'm getting a compile error: use
of undeclared identifier 'pvt'.

I've found similar reports for other versions (asterisk-11 and dongle;
macports; a couple others), but nothing for 12.4.

Any suggestions to fix the issue?

Thanks in advance.

You are building Asterisk using the 'clang' compiler. At this time 
Asterisk does not support being built with it. You will need to ensure 
GCC is used instead.
