    5 # SYNOPSIS
    6 #
    7 #   AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
    8 #
    9 # DESCRIPTION
   10 #
   11 #   For every FLAG1, FLAG2 it is checked whether the compiler works with the
   12 #   flag.  If it does, the flag is added FLAGS-VARIABLE
   13 #
   14 #   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
   15 #   CFLAGS) is used.  During the check the flag is always added to the
   16 #   current language's flags.
   17 #
   18 #   If EXTRA-FLAGS is defined, it is added to the current language's default
   19 #   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
   20 #   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
   21 #   force the compiler to issue an error when a bad flag is given.
   22 #
   23 #   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
   24 #
   25 #   NOTE: This macro depends on the AX_APPEND_FLAG and
   26 #   AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
   27 #   AX_APPEND_LINK_FLAGS.
