Matt Jordan commented on ASTERISK-20850:
----------------------------------------

We are well aware that RAII_VAR uses gcc extensions. The purpose of the macro is to provide scoped cleanup of local variables; this has been immensely useful throughout the codebase. This was an intentional decision during the development of Asterisk 11, as many portions of the codebase benefited from the use of the RAII_VAR macro.

> Nested functions are a GCC extension that is not sanctioned by C standards, thus the use of them is non-portable.  Specifically, CLANG does not support them.  CLANG is used by OSX, current versions of FreeBSD, and NetBSD is experimenting with it.  The RAII_VAR macro in include/asterisk/utils.h creates nested functions.  This prevents Asterisk 11.* from compiling with CLANG.
