Generally for me the mrproper has been needed when switching between archs or configs that leave generated files that pollute the build of others. Also a typical case is during certain bisects. It has happened to me many times to completely fail a bisect due to not cleaning everything. With that said I agree that cleaning by default is painful and I also hate doing that. So maybe better get rid of it indeed, and leave it to the user to decide to clean or not. Acked-by: Willy Tarreau <w@xxxxxx> Willy
