#
# SYNOPSIS
#
#   AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
#
# DESCRIPTION
#
#   For every FLAG1, FLAG2 it is checked whether the compiler works with the
#   flag.  If it does, the flag is added FLAGS-VARIABLE
#
#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
#   CFLAGS) is used.  During the check the flag is always added to the
#   current language's flags.
#
#   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: This macro depends on the AX_APPEND_FLAG and
#   AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
#   AX_APPEND_LINK_FLAGS.
