-From: Jo-Philipp Wich <jo@mein.io>
-Date: Wed, 9 Dec 2020 12:04:04 +0100
-Subject: [PATCH] build: prevent conflict with official AX_LIB_READLINE macro
-
-On systems where the official AX_LIB_READLINE (ax_lib_readline.m4) is
-present in a globally shared autoconf include directory, auto(re)conf
-will prefer including that offical version over the local variant due
-to the offical macro having a higher serial number.
-
-As a consequence, @READLINE_LIBS@ will not be substituted in *.in files,
-eventually failing the compilation with errors similar to:
-
-    gcc: error: READLINE_LIBS@: No such file or directory
-
-Avoid this problem by renaming the incompatible local macro to
-AX_LIB_READLINE_LLDPD which is sufficient to prevent any clashes.
-
-We encountered this problem on OpenWrt which uses GNU autoconf-archive
-to provide commonly used M4 macros through a global include directory,
-which happens to ship AX_LIB_READLINE as well.
-
