(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 preprocessor's default -# flags when the check is done. The check is thus made with the flags: -# "CPPFLAGS EXTRA-FLAGS FLAG". This can for example be used to force the -# preprocessor 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_{COMPILE,LINK}_FLAG. -# -# LICENSE -# -# Copyright (c) 2008 Guido U.
