When I built libvirt recently, I saw a warning go by: (with cutting edge automake-1.12a) configure.ac:83: warning: macro 'AM_PROG_CC_STDC' not found in library This fixes it: From: Jim Meyering <meyering(a)redhat.com&gt; Date: Sat, 26 May 2012 11:21:47 +0200 Subject: [PATCH] maint: avoid new automake warning about AM_PROG_CC_STDC * configure.ac (AM_PROG_CC_STDC): Stop using this macro. It provokes warnings from newer automake and is superseded by autoconf's AC_PROG_CC, which we're already using. --- configure.ac | 1 - 1 file changed, 1 deletion(-) diff --git a/configure.ac b/configure.ac index 5d06b47..54f51ee 100644 --- a/configure.ac +++ b/configure.ac @@ -80,7 +80,6 @@ dnl Checks for C compiler.
