+Subject: [PATCH] Remove references to dropped `sys_nerr` & `sys_errlist` for
+ `glibc-2.32` compat
+
+According to the release-notes[1], `strerror(3)` should be used. This is
+already the case, however the source tries to be backwards-compatible by
+supporting `sys_nerr` & `sys_errlist` which breaks compilation
+unfortunately.
+
+Simply using `strerror` fixes the problems.
