I don't think we need any fixes for this check - it's a tricky field, and we should let the user decide how to resolve these warnings.

I hope `float` types will be an option for this check in the future. Even better if we could have 2 options - one to enable integers, the other to enable floats. To achieve this, we could the check name to e.g. `portability-avoid-platform-specific-fundamental-types` in advance.
