System details

• OS/Platform name and version: Windows 11 23H2
• Rust version (if building from source): rustc --version: rustc 1.78.0
• Notify version (or commit hash if building from git): v4.0.X

No other details are relevant as this is a build-time issue.

What you did (as detailed as you can)

In a word: nothing. Users started reporting that using cargo install for a project I maintain no longer worked, so I investigated it. This has lead me here.

To be explicit: if you attempt to compile a project that is using notify v4 without a lock file, it will currently fail outright. This includes projects like cargo-watch, which use v4 of Notify.

What you expected

I expect that projects using notify v4 will compile, ideally.

What happened

Notify version 4 will fail to compile because it lacks the std and winerror features of winapi. Up until relatively recently, these features were enabled by a downstream dependency named winapi-util. They no longer are, which has caused the missing features to become obvious.
