+Subject: [PATCH 4/6] Restore compatibility to dietlibc, klibc, musl libc after commit 4f1b108
+
+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:
