You currently can't as long as the source files are different.

And even with the same source file it is difficult, since the parser will 
always parse only one branch from an IFDEF.

   THANDLE = Handle;
   THANDLE = Pointer;

Cannot be parsed correctly. Same for library units with different calling conventions etc.
