When using #[repr(C] on an enum in Rust, its size used to be 32-bits. However, rust-lang#107592 changed it to the target's c_int size, which is 64-bits for SBF.

As a consequence, the enum size is inconsistent between versions of the platform tools. A #[repr(C)] enum was 4 bytes in v1.37 and became 8 bytes in v1.39. This PR sets the enum size for 32-bits in SBF, as it used to be before the change.
