If you create a symbolic link on Windows 7 to a UNC path

mklink /d link \\server\share\dir

then use QDir()::canonicalPath to get the expanded path this is wrong. The issue is the code of readSymLink this uses DeviceIoControl to get the value of
the link. When a UNC path is used the result is ??\UNC\server\share\dir and the code current does not remove the UNC and replace by \. This result in the returned path being incorrect.

A possible fix is to do something like

if(result.startsWith(QLatin1String("\\??\\UNC
")))

{ result = result.mid(7); result.prepend(QLatin1Char('\\')); }

The 5.0 code seems to have the same problem
