Oh… that’s true. I forgot you were basically direct competitors in several areas with them.
I would love to produce a more abstract non-RO related test case for them, although my personal experience is that it doesn’t really matter, and much less for a case like this where I appear to be the only soul having this issue, ever.
I guess I am out of luck 
Hopefully you can get some kind of workaround, knowing better the needed project options and the changes between 9.2 and newer versions. I did a quick diff between the two but couldn’t really see between the real changes and the ones the IDE make to the project files.
Is it possible to rebuild the projects as you do with the installer (meaning: without having to open the IDE and so on?) The projects as they are right now, for instance, don’t include the Delphi option to generate the C++ files, although it is being set when compiling from the installer. I don’t know if there are some other things being changed that are not reflected on the projects per se.
