          Issue ID: 20521
           Summary: Checking for and getting empty variables on Wine / XP
                    fails
           Product: D
           Version: D2
          Hardware: All
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos
          Assignee: nobody@puremagic.com
          Reporter: dlang-bugzilla@thecybershadow.net

Phobos is relying on the behaviour of current Windows versions, but it wasn't always this way. This causes it to fail on XP and current versions of Wine (which emulates XP's behaviour).
