The report is actually
 https://bugs.freepascal.org/view.php?id=35267

As Werner noted earlier, the package .lpk files and parts of project
.lpi files should also be changed.
Namely:
- RequiredPackages
- Debugging/Exceptions
- RunParams/Modes

I am planning to do so in future. If Ondrej wants to look at it, fine
with me, too.
