Since all the macro name corresponds to ASCII representation of the hex numbers which gives a hint of what they means. For e.g. below 706e7473 means pnts. So similarly you can change vdb to 76646220.

set library already has member type iterator that is used here in line 76 std::set<std::string>::iterator s_it;. So no need to include iterator library.

That was fixed by adding the include.
