It would be much more than just unit Dos - you'd 
need changes in at least System (string 
manipulation routines), strings (StrPCopy) and 
many parts of the compiler itself.

Regarding unit Dos - providing PChar versions of 
some routines might be of general use, probably 
more useful than longstrings.
