+Subject: [PATCH] Fix build on arm64 linux.
+
+On arm64 linux, c_char is u8. CStr::from_ptr is documented to take an
+i8, but this is not accurate (see
+https://github.com/rust-lang/rust/issues/113735); instead, it takes
+c_char, which is sometimes but not always the same. One time it is
+different is on aarch64 Linux, so without this commit, cubeb-rs fails to
+build there.
