Add --enable-dev-mode=strict to configure.
Passing -Wshadow to gcc enables shadow warnings. From the gcc manual: Warn whenever a local variable or type declaration shadows another variable, parameter, type, or class member (in C++), or whenever a built-in function is shadowed. Asterisk will not currently compile with this option set, but a number of bugs have been discovered by enabling this flag on specific files. The long-term goal is to eliminate all of the suspect code that causes this warning to be emitted. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@358622 65c4cc65-6c06-0410-ace0-fbb531ad65f3
