5# SYNOPSIS
6#
7#   AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS])
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#   NOTE: This macro depends on the AX_APPEND_FLAG and
24#   AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
25#   AX_APPEND_LINK_FLAGS.
