I am using quilt to manage patches internally. Quilt creates dir .pc and stores unmodified files there. Since I made change in one of Config.src quilt made a copy in .pc/xxx.patch/xxx/Config.src. When I run make it calls gen_build_files.sh and it generates .pc/xxx.patch/xxx/Config.in. Now when I want to pop patch quilt thinks I have made changes to original xxx/Config.in. IMO the best solution is just to ignore hidden directories in gen_build_files.sh. This also results in shorter build time in case busybox is under git/svn versioning, since it avoids searching many directories for Config.src.
