//! Avoid using the `libc` crate to get C types since `libc` doesn't support
|
|
//! all the targets we need to support. It turns out that the few types we need
|
|
//! are all uniformly defined on the platforms we care about. This will
|
|
//! probably change if/when we support 16-bit platforms or platforms where
|
|
//! `usize` and `uintptr_t` are different sizes.

// Keep in sync with the checks in base.h that verify these assumptions.
