> 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.
