Maybe not relevant to coreutils, but including the list will help us know that the issue has come to a resolution. Make uses mtime (not ctime) for timestamp comparisons. Meanwhile, there is a project named remake that provides an easier way to debug GNU make behavior over a given makefile, by single stepping through commands and dependencies. > > Anyway, the Makefile problem has been fixed.
