qmake (QFileInfo::absolutePath:) does not recognise Windows Vista/7 directory symlink correctly.

When target directory (eg: include path) is given as symlink (eg: c:\dev\qt\current -> c:\dev\qt\4.6.2), qmake ignores entire symlink part except actual target part, with message of "QFileInfo::absolutePath: Constructed with empty filename"

For example,

c:\dev\tbb
<DIR> .
<DIR> ..
<DIR> 3.0
<SYMLINKD> current [3.0]

when target include path is given as "INCLUDEPATH=c:\dev\tbb\current\include" which should stay as it is, but it returns to in makefile as "-I 3.0\include'

It wasn't happen in at least 4.5.2
