FastMM4 & C++Builder 11.3 & IntraWeb 15.6.7

[StephanM]

I've made some progress.
This is an older project, using the initial project options.
I changed it to use the Clang compiler (Project > Options > C++ Compiler > deselect Use 'classic' Borland compiler), and most errors went away.

So I created an empty project, and no errors!
- I did select FastMM4 from the project wizard. BUT, to use FastMM4, do I still need to follow the instructions in FastMM4BCB.cpp and add the FastMM4 files manually?
- How can I tell if FastMM4 is used?

Thanks
