Installation failed for unknown reason

[Phosphorus15]

Simply typing cargo install cargo-clone, encountered mysterious build failure.

Rustc : rustc 1.36.0 (a53f9df32 2019-07-03)

Toolchain : stable-x86_64-pc-windows-gnu

The error messages are too long so I truncated it

It seems that the problem was caused by git2_sys, but this should have been fixed in its previous version.

Well, it turns out that using msvc toolchain instead of gnu ones solves the problem, But I'm still confused why gnu toolchain couldn't.
