- # SYNOPSIS
- #
- # AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS])
- #
- # 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.
- #
- # 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.
