Problem with 'basedir' on Windows

[goozak]

Using Windows 10 with PHP 7.2 on IIS.

When I set basedir to a specific folder (such as C:\Test), the file list is displayed but 'file access functions', such as filesize and filemtime, throw a stat failed warning.

Seems like the basedir path should be used for these: warning mentions ./filename but I think it should be C:\Test\filename).
