I see the following way to implement it:

For example the compiler was found the following declaration of global propery:

property DrawMode: integer read GetDrawMode write SetDrawMode;

If GetDrawMode and SetDrawMode was not declared before, the compiler assumes that declaration is standard:

procedure SetDrawMode(const Value: integer);
function GetDrawMode: integer;

The compiler can internally declare setter and getter and mark them like compilerproc (or in other way) to hide from global 
namespace.
