Headers not found on msvc abi

[Sirius902]

With the following program on Windows (I have exe.linkLibC(); in the build script)

const print = @import("std").debug.print;
const c = @cImport(@cInclude("stdio.h"));

pub fn main() void {
    print("{}\n", .{c.EOF});
}

It prints -1 as output with -Dtarget=native-native-gnu but on -Dtarget=native-native-msvc I get the following compiler error:

.\src\main.zig:2:11: error: C import failed
const c = @cImport(@cInclude("stdio.h"));
          ^
.\zig-cache\o\554df7d82185a847c43862003dfc7d3c\cimport.h:1:10: note: 'stdio.h' file not found
#include <stdio.h>
         ^
.\src\main.zig:5:21: note: referenced here
    print("{}\n", .{c.EOF});
                    ^

Here is my output from zig libc:

Edit: I'd like to add that this used to work on older Zig versions. Currently I'm on zig-windows-x86_64-0.9.0-dev.117+0d022eb1d.

I would like to add that directly running zig run -lc -Dtarget=native-native-msvc src/main.zig instead of invoking the build script does not have this problem. I checked to make sure when running the build script (with zig build run) and -lc is passed to zig build-exe but even despite that it can't find the headers.

Now on 0.9.0-dev.250+c6844072c.
