From ba932c009e8fc45e23efe1dfbc0f179c40af6923 Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Fri, 24 Apr 2009 18:44:11 +0200 Subject: [PATCH] use AC_CHECK_SIZEOF rather than AC_TRY_COMPILE for long long detection AC_CHECK_SIZEOF does first detect if the type is available and detects its size. Use it, rather than hand crafted function with AC_TRY_COMPILE.
