# Rebuilding this configuration
# -----------------------------
+# On the use of stamps:
+# Consider the example of tree-check.h. It is constructed with build/gencheck.
+# A simple rule to build tree-check.h would be
+# tree-check.h: build/gencheck$(build_exeext)
+# $(RUN_GEN) build/gencheck$(build_exeext) > tree-check.h
+#
+# but tree-check.h doesn't change every time gencheck changes. It would the
+# nice if targets that depend on tree-check.h wouldn't be rebuild
+# unnecessarily when tree-check.h is unchanged. To make this, tree-check.h
+# must not be overwritten with a identical copy. One solution is to use a
+# temporary file
+# tree-check.h: build/gencheck$(build_exeext)
+# $(RUN_GEN) build/gencheck$(build_exeext) > tree-check.h
+# $(SHELL) $(srcdir)/../move-if-change tmp-check.h tree-check.h
+#
+# This solution has a different problem. Since the time stamp of tree-check.h
+# is unchanged, make will try to update tree-check.h every time it runs.
+# To prevent this, one can add a stamp
+# tree-check.h: s-check
+# s-check : build/gencheck$(build_exeext)
+# $(RUN_GEN) build/gencheck$(build_exeext) > tree-check.h
+# $(SHELL) $(srcdir)/../move-if-change tmp-check.h tree-check.h
+# $(STAMP) s-check
+#
+# The problem with this solution is that make thinks that tree-check.h is
+# always unchanged. Make must be deceived into thinking that tree-check.h is
+# rebuild by the "a: s-a" rule. To do this, add a dummy command:
+# tree-check.h: s-check; @true
+# s-check : build/gencheck$(build_exeext)
+# $(RUN_GEN) build/gencheck$(build_exeext) > tree-check.h
+# $(SHELL) $(srcdir)/../move-if-change tmp-check.h tree-check.h
+# $(STAMP) s-check
+#
+# This is what is done in this makefile. Note that mkconfig.sh has a
+# move-if-change built-in
+
