procedure update_unit_symtable_options;
var
st: tsymtable;
begin
st:=owner;
while not(st.symtabletype in [globalsymtable,staticsymtable]) do
st:=st.defowner.owner;
include(st.tableoptions,sto_has_classhelper);
end;

if objecttype in [odt_classhelper,odt_objccategory] then
    update_unit_symtable_options;

This will work faster because loop and the function call will run not 
for all object types.
