os.mkdir() on Windows 11 creates a different named directory than specified by path

[fluxprox]

Describe the bug

My base development environment is Linux but I'm working on cross platform tooling in V and discovered that on Windows 11 os.mkdir(path) is creating a directory that does not match the specified path.

Reproduction Steps

import os

fn main() {
    path := os.abs_path('newdir')
    if !os.exists(path) {
        os.mkdir('newdir')
    }
}

Expected Behavior

Windows should have created the directory specified by path 'newdir'

Current Behavior

Windows created a directory named 'C' instead of 'newdir'

Possible Solution

Temporary work around was to directly use C.CreateDirectory() on Windows without converting the path string using to_wide()

import os

fn main() {
    path := os.abs_path('newdir')
    if !os.exists(path) {
        $if windows {
            C.CreateDirectory(path.str, 0)
        }
    }
}
