I don't see the actual user of the define. Define itself will not generate the warning. You need to actually use it outside of preprocessor. I don't understand who would use it in 32-bit code. Maybe fixing it this way masking other issue. That said, I don't object the change itself. We just need to understand the context more. -- Kiryl Shutsemau / Kirill A. Shutemov
