GetVolumePathNameW is causing some incompatibity problems with some Windows applications such as Native Instruments "Native Access" because of an inability to handle path names containing forward slash's whereas the Windows GetVolumePathName's behaviour handles path names with both forward and back slash's.
Tested on Debian Stretch and Windows Vista

GetVolumePathNameW is causing some incompatibity problems with some Windows applications such as Native Instruments "Native Access" because of an inability to handle path names containing forward slash's whereas the Windows GetVolumePathName's behaviour handles path names with both forward and back slash's. This v2 patch also includes GetVolumePathNameW relative path handling.

v2 breaks tests, revert to v1 or don't use v2. GetVolumePathNameW is causing some incompatibity problems with some Windows applications such as Native Instruments "Native Access" because of an inability to handle path names containing forward slash's whereas the Windows GetVolumePathName's behaviour handles path names with both forward and back slash's.

Hi Mark,
Thanks for your contribution. You need to rework this series into one patch. Currently it's three patches which essentially revert each other. It might be a good time to learn how to use git rebase -i (though there are other ways to achieve this in this case).
Also note that the plural of slash is slashes...
Huw.
