+From b668cb75cb7e72ff92055209130d4cd4b3cacbdb Mon Sep 17 00:00:00 2001
+From: Thorsten Glaser <tg@mirbsd.org>
+Date: Fri, 20 Jun 2014 10:56:27 +0000
+Subject: [PATCH 4/9] Restore compatibility to dietlibc, klibc, musl libc after
+ commit 4f1b108
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Each C library has their own way to define off_t, and the <features.h>
+header is nonstandard and specific to the GNU libc and those that clone
+it (uClibc). Fefe’s dietlibc uses different flags, and klibc always uses
+a 64-bit off_t (like the BSDs); musl libc cannot be recognised using cpp
+instructions, so we assume 64 bit there (and on unknown C libraries) and
+leave it to the user to submit a follow-up fix if we guess wrong. I also
+added a static assertion to verify the 64 bit guess is correct.
+
+It would be really better using a configure script for this instead.
+
+Fixes:
+| CC lib/libmtd.o
+| In file included from ubi-utils/ubiutils-common.c:35:0:
+| ./include/common.h:29:22: fatal error: features.h: No such file or directory
+| #include <features.h>
+| ^
+| compilation terminated.
