The AC_HEADER_STDC macro<br>> is now a no-op (and is not used at all within Autoconf anymore), so<br>> that change is likely what made the first use of AC_EGREP_HEADER the<br>> one inside the if condition, causing the observed results.<br><br>The implication is that the test does nothing anyway, and due to it<br>being a no-op from 2.70 onwards, results in the required not being set<br>to yes, resulting in ./configure to fail.<br><br>Change-Id: Ic1ff38d87f791fbf1f2a80512f81bb7110392460<br>Signed-off-by: Jaco Kroon <jaco@uls.co.za><br>---<br>M configure<br>M configure.ac<br>2 files changed, 0 insertions(+), 121 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.asterisk.org:29418/asterisk refs/changes/58/15358/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/configure b/configure</span><br><span>index 9b96fde..586f612 100755</span><br><span>--- a/configure</span><br><span>+++ b/configure</span><br><span>@@ -13091,122 +13091,6 @@</span><br><span> as_fn_error $?
