features 启用了 win7，但是编译使用的是默认的 xp #29
Description
`
[target.'cfg(target_os = "windows")'.build-dependencies]
thunk-rs = { version = "0.3.5", features = ["win7", "lib", "subsystem_windows"] }
`
编译结果：
warning: [email protected]: VC-LTL5 Enabled: 5.2.3790.0(x64)
warning: [email protected]: YY-Thunks Enabled: WinXP(x64)
warning: [email protected]: Lib Mode Enabled!
这应该是不对的吧
