-#   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
-#
-# DESCRIPTION
-#
-#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
-#   added in between.
-#
-#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
-#   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
-#   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
-#   FLAG.
-#
-#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

-#   AX_APPEND_LINK_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
-#
-# DESCRIPTION
-#
-#   For every FLAG1, FLAG2 it is checked whether the linker works with the
-#   flag.  If it does, the flag is added FLAGS-VARIABLE
-#
-#   If FLAGS-VARIABLE is not specified, the linker's flags (LDFLAGS) is
-#   used. During the check the flag is always added to the linker's flags.
-#
-#   If EXTRA-FLAGS is defined, it is added to the linker's default flags
-#   when the check is done.  The check is thus made with the flags: "LDFLAGS
-#   EXTRA-FLAGS FLAG".  This can for example be used to force the linker 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_LINK_FLAG.
-#   Please keep this macro in sync with AX_APPEND_COMPILE_FLAGS.

-# SYNOPSIS
-#
-#   AX_REQUIRE_DEFINED(MACRO)
-#
-# DESCRIPTION
-#
-#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
-#   been defined and thus are available for use.  This avoids random issues
-#   where a macro isn't expanded.  Instead the configure script emits a
-#   non-fatal:
-#
-#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
-#
-#   It's like AC_REQUIRE except it doesn't expand the required macro.
-#
-#   Here's an example:
-#
-#     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])
