How to debug DCU in Borland Delphi 2006?

Question

I use Borland Delphi 2006 (folder name: C:\Program files\borland\BDS\4.0), and I want to enable debug DCUs. Where can I find this option? in tools->options->debugger options it doesn't exist.

Note: I have also Embarcadero developer studio, but I hate it. My project is written under BDS 4.0 too.

You may be confused by the fact that debug .dcu's is not a debugger option, but a compiler option.

Is the compiler the one which generates and includes the symbols required to debug inside the Delphi RTL/VCL.

The debug DCUILs (.NET) or DCUs (Win32) contain debug information and are built with stack frames. When this option is checked, the compiler prepends the debug DCUIL/DCU path to the unit search path specified in Debug Source Path on the Directories/Conditionals page.

The option is under the compiler options in each project, in:

Project\Options\Compiler\Debugging\Use debug DCUs

Note I really don't have BDS2006 right now, the closest version I have is BDS2007, but AFAIK the option is named the same.
