Hello,

I would like to have a very simple additional property for tComponent.
The "Tag" property let you store a user longint value (4 bytes). I
often used this "Tag" as a pointer where I store user data in a
record. But this does not work on 64 bit OS with 8 byte pointers. It
would be the simpliest way to create an additional property TagPointer
or TagPtr : pointer. There's another proposal to change the Tag
property
http://www.mail-
archive.com/lazarus@lists.lazarus.freepascal.org/msg14578.html
but this makes problems with old code. I would prefer an additional
property and variable.

tag already has been extended to 64-bit out of Delphi compatibility a
few weeks ago
