i686-pc-windows-gnu executables depend on additional DLL

[mati865]

I tried this code:

fn main() {
    println!("Hello, world!");
}

I expected to see this happen: Get portable executable depending only on C:/Windows/System32 libraries.
Instead, this happened: Since nightly-2020-03-15 (most likely #67502) building with i686-pc-windows-gnu target results in executable that depends on libwinpthread-1.dll beside typical libraries.
