UPGRADING NOTE: #2804, we invert the order of --cfgs passed by our build.rs script. This will be transparent to cargo users, but if you vendor zerocopy and build it by invoking rustc directly, you will need to update your --cfgs. Assuming you're on a relatively recent toolchain, you should simply stop passing any --cfgs when building zerocopy. For more details, see #2259.
