quickcheck depends on WinAPI?

[vi]

 Downloading rand v0.3.11 (reasonable - quickcheck is a randomized test)
 Downloading log v0.3.2 (reasonable - it's omnipresent)
 Downloading winapi v0.2.4 ( ??? )
 Downloading quickcheck v0.2.24

[BurntSushi]

Please look at the Cargo.toml for the direct dependencies: https://github.com/BurntSushi/quickcheck/blob/master/Cargo.toml#L16-L19 There is no winapi.

Therefore, winapi must be a dependency of one of quickcheck's dependencies.

In this case, it is a dependency of rand.

winapi is an empty crate on all non-Windows platforms. The maintainers of some crates (rand, in this case) prefer to just unconditionally depend on it than to get into platform-specific dependencies. See this for more details. rust-random/rand#65
