[php-src] Issue #8393: Can't understand mount point directories on Windows

Issue: https://github.com/php/php-src/issues/8393 Comment Author: cmb69 > I think I'll need to setup a suitable environment for debugging. Sorry, I won't have time for this, especially since this appears to be a low priority issue, and I still think this is an issue with rclone. > Anything I can help with, I'll be glad to. Consider to [set up a development environment](https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2), and [do some debugging](https://github.com/php/php-sdk-binary-tools#debugging-php). I suggest to start by setting a breakpoint at https://github.com/php/php-src/blob/52a18a6620649c6c9382701aaf803e1a6346cddd/Zend/zend_virtual_cwd.c#L670
