<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I feel that configure should create a #define for the type of nested procedure supported. This should use results of configure (#ifdef HAVE_CLANG_BLOCKS), instead of implementing it's own direct tests.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Hm. I'm not sure how much better that makes this, since I find parsing out a configure.ac file to be much harder than the #defines in a header.
What specifically are you envisioning? Right now, I'm having a hard time determining how this would look in the configure script and how it would be reflected here.</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;">The idea is that configure is responsible for testing features and reporting what was found, so we shouldn't attempt to duplicate the logic of those tests. The tests performed in configure are better anyways.
In configure.ac where it finds working CLANG support, we want to add:
AC_DEFINE([HAVE_CLANG_BLOCKS], 1, [Define to 1 if your compiler supports CLANG blocks.])
And when it finds GCC nested functions:
AC_DEFINE([HAVE_GCC_NESTED_FUNCTIONS], 1, [Define to 1 if your compiler supports GCC nested functions.])
Then when you run bootstrap / configure, you will get the appropriate #define / #undef in asterisk/autoconfig.h.
Then in asterisk/utils.h:
#if defined(HAVE_CLANG_BLOCKS)
/* CLANG support code */
#elif defined(HAVE_GCC_NESTED_FUNCTIONS)
/* GCC support code */
#else
#error
#endif</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>
