cargo-c v0.7.1+cargo-0.49: compiling fails (de.rs:530:63 - type annotations needed)

Trying to compile cargo-c in media-autobuild suite (MSYS2/MinGW) as prerequisite of rav1e encoder:

Same problem, it seems that a dependency of cargo has updated with incompatible API change.
Try cargo install cargo-c --locked.

Update: Found upstream issue rust-lang/cargo#9101

[lu-zero]

v0.7.2 should had addressed that. Is it still a problem?

[LigH-de]

Uh, yes, I closed the upstream issue but forgot this.
