Subject: [RFC/PATCH] autoconf: Do not build "http-push" without expat headers

From: Allan Caffee <[email-masked]>
Date: Wed, 22 Apr 2009 07:58:01 -0400

Simply linking against expat does not guarantee successful compilation.
Check for development headers before attempting to compile the dependant
binaries.
