+2025-08-16) project has a different take on patching. It uses preprocessor directives to decide
whether or not to include a patch during build time. Essentially this means that this build, for
better or worse, contains both the patched _and_ the original code. The aim being that you can
select which patches to include and the build will contain that code and nothing more.
