commit 3f683aadcd03c311c1d987ab847a77dbe3fb2bf1

    When making a tempdir for windows unit tests, avoid an extra backslash
    
    The extra \ is harmless, but mildly unpleasant.
    
    Fixes 12392; bugfix on 0.2.2.25-alpha where we started using
    GetTempDir().  Based on a patch by Gisle Vanem.
