"Argument list too long" with many files on Windows

[SimonSapin]

https://github.com/servo/mozangle/tree/ee3f46cc4e6a990634d3cab4d49d1ebfdb785d22 uses the cc crate, and cargo test works on both Linux and Windows for me.

When adding --features egl however, compilation fails on Windows with the error below. This feature is Windows-only, but as far as the cc crate is concerned it mostly adds a bunch more source files.

Internal error occurred: Command "C:\[…]\lib.exe" [many arguments…] with args "lib.exe" failed to start.

When I copy/paste the command into a shell, the output is:

Argument list too long

Could this crate do something like rust-lang/rust#47507 ?

I could compile with #293.
