I always thought that fpc supports a.x and b.x for differenciating them, 
but never used it. Perhaps even a type definition in your program as

type
         Graphic = a.x;
         Incognite = b.x;

allows you use both without any problem.

P.S. From freepascal.com/advantage.html; Is this still true??

"Each unit has it's own identifiers In Pascal you never need to worry about 
polluting the namespace, like in C where an identifier needs to be unique 
accross the entire program. No, in Pascal each unit gets it's own namespace 
and that's very relaxed."
