+By default libc uses private fields in structs in order to enforce a certain
+memory alignment on them. These structs can be hard to instantiate outside of
+libc. To make libc use `#[repr(align(x))]`, instead of the private fields,
+activate the *align* feature. This requires Rust 1.25 or newer:

+```toml
+[dependencies]
+libc = { version = "0.2", features = ["align"] }
