From fdc3918b26b86e90273be709ae3513425ba5822f Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN\"" Date: Thu, 18 Oct 2012 00:31:53 +0200 Subject: [PATCH] configure: check for sys/queue.h and CIRCLEQ_XXX mconf and nconf need the CIRCLEQ_XXX macros defined in sys/queue.h, so check for them, as they are missing on legacy systems (eg. Debian potato). Signed-off-by: "Yann E.
