+# The following rules insure that the Makefile is up-to-date by rerunning
+# various autoconf components (although not all versions of make assume
+# that the makefile is implicitly a target).  We use time stamp files to
+# keep track of the most recent update of H5config.h.in and H5config.h
+# because autoheader and config.status don't update the modification time
+# if the contents don't change.
