 to encounter is:
  "Incompatible types: 'System.WideChar' and 'JwaWinType'.WideChar" where WideChar
  is only an example. This is due to the fact that the RTL (e.g. System.pas or
  Windows.pas) defines the type WideChar differently from WinType.pas. To solve
  this simply change the declaration in JwaWinType.pas to become an alias for the
  type in System.pas (or Windows.pas). For example
  Before:
  <pre class=syntax>
  <b>type</b>
    DWORD = Longword;
  </pre>
  After:
  <pre class=syntax>
  <b>type</b>
