What if unitaa needs recompilation, and it is not in the dir it was originally
compiled in. .\some\other\place then has a different meaning.

Specially if the relative paths are short (like ..\src\ or so), there is still
quite some room for clashes. 

That is probably the reason it is mainly used in the DPR, there relative
paths can be interpreted relative to the .dpr, and .dpr's are generally not
recompiled in other directories.
