#define forceinline __inline__ __attribute__((always_inline))
#define ensure_forceinline __attribute__((always_inline)) // inline or die
To see if they would help forcing clang to inline</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I gave it a shot, and clang still believes that the functions are re-defined.
There may be a magical invocation to get clang to believe that these inlinings should occur, but I'm not sure what it is.</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>

* Compiled Asterisk without --enable-dev-mode using clang. Asterisk compiles, links, and executes.
Note that you will need the BlocksRuntime to run Asterisk when it is compiled with clang.</pre>
