The compiler doesn't use a unit's same directory for searching units. It is
using project's file directory for searching and then any directories
referenced is -Fu switch.
Thus the same list of search directories is used for any unit in the
project (and that's causing the requirement to have all unit names unique
per project)

Changing the structure of a project is a big NO. For a number of reasons:
* a compiler change should never force a developer to make any major
changes in the project sources or structure;
* it might be impossible to merge two different components into the same
directory or sub directory, because of the conflicting file names;
* the external tools (i.e. SVN) might require two components be in a
separate folders (i.e. for syncing sources);
-so I'd removing rule #1 as a solution here.
As well as rule #2, since it's not an option to change 3d party code (even
just to introduce an alias reference). Don't forget that you've mentioned
it earlier yourself.

thanks,
Dmitry
