<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Replacing this with:
AC_MSG_ERROR("nested-functions is required for gcc")
Caused configure to fail:
checking for -Wshadow... yes
checking for -march=native support... yes
checking for gcc -fnested-functions... configure: error: "nested-functions is required for gcc"
Even though I did have nested functions....
So that's weird.

<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'm actually not sure what -fnested-functions would even do. My google-foo is failing me on its use with GCC (which appears to not understand it), and since we only set that on the "false" path (that is, we failed to compile a program with a nested function), I'm not sure how it would help.
As it is, I think I will put an AC_MSG_ERROR in the 'false' path of the compilation.</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;">So this finding can be dropped, I was wrong. This line (and the next line with [AST_NESTED_FUNCTIONS=]) is the block that is run if AC_COMPILE_IFELSE succeeds without the -fnested-functions gcc flag. So we're not checking for nested functions, we're checking if nested functions fail without the flag.
Now if AC_COMPILE_IFELSE does fail we assume that it would succeed with the GCC flag. In theory we should verify that it would work with -fnested-functions. But that is a separate issue.</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>
