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