Delphi XE2 cannot find ComObj.dcu where did it go?

Question

I'm trying to install the jvcl from source, but I'm getting an error in line #1267 of unit JvInterpreter;

uses
  TypInfo,
  {$IFDEF JvInterpreter_OLEAUTO}
  OleConst, ActiveX, ComObj,

So I removed ComObj from the uses and waited for the error further down the line:

There's an error concerning EOLEError, which is part of OleAuto I added that and hoped for the best, but....

I get an error on this line #1799:

DispatchInvoke(IDispatch(Dispatch), CallDesc, PDispIDList(@DispIDs[0]), ParamTypes, Result);

So the question is: what happened to ComObj and what unit do I need for DispatchInvoke in XE2?

Simply add system.win i.e. instead of comobj use system.win.comobj

The solution is to change the uses to use a fully qualified name:

uses
  TypInfo,
  {$IFDEF JvInterpreter_OLEAUTO}
  OleConst, ActiveX, 
  {$IFDEF VER230} system.win.ComObj, {$ELSE} ComObj, {$ENDIF}

Now it compiles without error.
See: What is the compiler version for Delphi 2010?

Alternatively, you can add "System.Win" to the project's list of available Unit Scope Names, then you do not have to change the original code at all. – Remy Lebeau Dec 12 '11 at 21:42
