-#
-# DESCRIPTION
-#
-# Check whether the given FLAG works with the current language's compiler

-#
-# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on

-# If EXTRA-FLAGS is defined, it is added to the current language's default

-# 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.
