[SVN commits to the Asterisk project]

Author: dlee

New Revision: 402192

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=402192
Log:
Backport r373119 from 11 to go along with RAII_VAR support.

In order to use nested functions on some versions of GCC (e.g. GCC on OS X),
the -fnested-functions flag must be passed to the compiler. This patch adds
detection logic to ./configure to add the flag if necessary.
