Yes, cross unit "type overloading" is still a problem in FPC. I've done 
some preparations to solve this (the compiler now keeps track whether a 
symtable contains a generic), but I've yet to implement the final lookup 
system for this.

I already have fixed the gendef problems you reported locally, but I 
need to find the time to write a nice commit message, because I've 
changed the complete implementation of constraints.
