bindgen generating `i64` instead of `u64`

[redeexpressos]

Input C/C++ Header

#define UAVCAN_PROTOCOL_GETNODEINFO_REQUEST_SIGNATURE (0xEE468A8121C46A9EULL)

Bindgen Invocation

    let bindings = bindgen::Builder::default()
        .clang_arg("-Iexternal/libcanard")
        .header("wrapper.h")
        .generate()
        .expect("Unable to generate bindings");

pub const UAVCAN_PROTOCOL_GETNODEINFO_REQUEST_SIGNATURE: i64 = -1277181157091022178;

Expected Results

Shouldnt it generate an u64?
