++# ===========================================================================

++# ===========================================================================
++#
++# SYNOPSIS
++#
++#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
++#
++# DESCRIPTION
++#
++#   Check whether the given FLAG works with the current language's compiler
++#   or gives an error.  (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.
