The modified Util::make_relative_path implementation added in 8223ed38abd9cf75ab75cb19dc2081c44bf568d0 seems to have introduced some some test failures on Windows when I run the unit tests locally.
I suspect this is in part due to
Stat::same_inode_as, which gives incorrect results on Windows because
st_ino is not populated by the
stat() implementation in either the legacy msvcrt.dll (still used by mingw-w64) or ucrtbase.dll (used by Visual Studio).
st_dev is populated with a distinct value for each Win32 drive letter, so
Stat::same_inode_as can distinguish between two files on different drives, but that's it. I suspect these failures are not seen in CI because the GitHub runners use a working directory not under the C:\ drive to check out the repo and run the tests.
