(Warnings, however, are ignored) 2725 # 2726 # ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on 2727 # success/failure. 2728 # 2729 # If EXTRA-FLAGS is defined, it is added to the current language's default 2730 # flags (e.g. CFLAGS) when the check is done. The check is thus made with 2731 # the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to 2732 # force the compiler to issue an error when a bad flag is given. 2733 # 2734 # INPUT gives an alternative input source to AC_COMPILE_IFELSE. 2735 # 2736 # NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this 2737 # macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG. 2738 # 2739 # LICENSE 2740 # 2741 # Copyright (c) 2008 Guido U.
