+# We need DerivedConstants.h in order to make dependencies in the RTS
+# sources, so 'make boot' here should behave like 'make all'.
+#
+# However, note that we should do this only *after* 'make boot' has
+# created .depend in here; otherwise an out-of-date .depend file can
+# prevent 'make boot' from working, requiring manual removal of
+# .depend (see #1095). This is why the following target comes *after*
+# target.mk is included above (target.mk contains "boot :: depend").
+#
+boot :: all
