(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. -# -# 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.
