include and which symbols need to be `#define`d to get the actual data
structures that pass through to the kernel system calls. Some C libraries
preset alternate versions for binary compatibility and translate them on the
way in and out of system calls, but there is almost always a `#define` that can
get the real ones.
See `types_darwin.go` and `linux/types.go` for examples.

When preparing any change that is permitted by Go 1 compatibility
but may nonetheless break some existing programs,
we first engineer the change to keep as many existing programs working as possible.
For the remaining programs,
we define a new GODEBUG setting that
allows individual programs to opt back in to the old behavior.
A GODEBUG setting may not be added if doing so is infeasible,
but that should be extremely rare.
