title: How to also prepare for 64-bits when migrating to Delphi 2010 and Unicode
body: <p>As 64 bits support is not expected in the next version it is no longer an option to wait for the possibility to migrate our existing code base to unicode and 64-bit in one go.
  However it would be nice if we could already prepare our code for 64-bit when doing our unicode translation. This will minimize impact in the event it will finally appear in version 2020.
  Any suggestions how to approach this without introducing to much clutter if it doesn't arrive until 2020?</p>
