 #          Create programs.

 # HACK ALERT
 #
 # 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.

	# 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.
