# create the directory, then create the file.  The second file will be
# created inside the directory; but on some filesystems, creating the
# file inside the directory then updates the 'last modified' timestamp
# of the directory.  So next time you run make, the directory is
# 'newer' than the first file, and because the first file depends on
# the directory, make will determine that it needs to be updated,
# triggering a spurious recreation of the file.  If you also have
# auto-dependencies turned on, this might in turn cause recompilation
# and further spurious rebuilding to happen.
