+# The only purpose of this rule is to pass Mozilla's Tinderbox depend
+# builds (http://tinderbox.mozilla.org/showbuilds.cgi).  Mozilla's
+# Tinderbox builds NSPR continuously as part of the Mozilla client.
+# Because NSPR's make depend is not implemented, whenever we change
+# an NSPR header file, the depend build does not recompile the NSPR
+# files that depend on the header.
+#
+# This rule makes all the objects depend on a dummy header file.
+# Touch this dummy header file to force the depend build to recompile
+# everything.
+#
+# This rule should be removed when make depend is implemented.
