Remove compilation and static analysis warnings #9
Description
This is a long-term issue.
The goal is to remove all static analysis warnings, and all warnings that happen during compilation.
As the time of writing (July 16th, 2023) there were over 100 compile-time warnings, and inummerable IDE warnings left in the project.
SuppressWarnings should only be used with a very good reason to do so. And even then, it probably shouldn't.
