Defining the "string" type in a unit (e.g. the ObjPas unit) is a bad 
idea if you want to keep the capability to change the "string" type on a 
per unit base as you can't change the compiled ObjPas unit. Also you'd 
need a unit for every string type that should be supported.
The proposal where "string" is changed based on some compiler 
option/define is better (though the question about its use or 
consequences is still not solved).
