Can't compile for target x86_64-pc-windows-gnu (ld: cannot find -lntdll)

[MegaBrutal]

I'm porting one of my Linux tools to Windows and it fails to compile when the postgres crate is added as a dependency. I opted for using target x86_64-pc-windows-gnu because x86_64-pc-windows-msvc would require me to install a large Visual Studio toolchain that I doubt I really need.

Here is a minimal project to reproduce the issue:

Cargo.toml:

[package]
name = "test-postgres"
version = "0.1.0"
edition = "2021"

[dependencies]
postgres = "0.19.4"

src/main.rs:

use postgres::{Client, NoTls};

fn psql_query_rows(db: &str, query: &str) -> Result<Vec<postgres::Row>, postgres::Error>
{
	Client::connect(&format!("host=localhost user=postgres password=postgres dbname={}", db), NoTls)?
		.query(query, &[])
}

fn main() {
	let query = "SELECT id,first_name,last_name FROM employee";
	println!("Query: {}\nResult: {:?}", query, psql_query_rows("postgres", query));
}

When I try to compile it, I get the following error:

error: linking with `x86_64-w64-mingw32-gcc` failed: exit code: 1

error: could not compile `test-postgres` due to previous error

So it can't link to ntdll, but I don't know why. I see the postgres crate depends on winapi and windows-sys, but if I try to directly use these crates, I can link to ntdll just fine, even with x86_64-w64-mingw32-gcc, so it seems postgres has a special circumstance which prevents that.

[sfackler]

There is nothing in this crate that references Windows in any way. This seems like a general issue with your cross compilation toolchain or an upstream dependency.

[MegaBrutal]

It seems tokio and parking_log references Windows libraries.

Maybe I should test these libraries alone as well and report the problem against them, in case one of them reproduces the problem.

I'm trying to compile on native Windows, by the way, in order to rule out cross-compile problems. Of course later I might switch to cross compiling as it would be more convenient.

All right, reproduced with tokio alone.
In fact, going further down the tree, I found the culprit is mio.
Aaaand... it's already reported there: tokio-rs/mio#1632.
Thank you!
