Build failure in empty project: expected enum winapi::ctypes::c_void, found enum std::ffi::c_void

[jamesgecko]

In a new project where junction is the only dependency, I get the following build failures on Windows 11 with Rust 1.67.0 (fc594f156 2023-01-24). I do not see these errors when running cargo build in the library directory; it's entirely possible I'm doing something wrong.

Similar failures seem to have happened in wezterm and tokio.

Sorry I couldn't reproduce your issue on local machine or CI either.

Could you recheck the issue. If the issue is continue to be your problem, could you
post your Cargo.lock file and rustc -Vv?

[tesuji]

I'm sorry. I'd have read your OP more carefully. I fixed the issue now.
