Sounds like my non-web hobby projects with Lazarus.

I don't do that, though. Even if technically possible, there are hidden
stuffs you have to be aware of. main() is only a specification in C
standard, where the user code starts. However, long before that, there's a
startup mechanism specific to each implementation. In GCC, this is _start,
absolutely non-portable. That's why the IMO better way is to communicate
over pipes via TProcess.
