ChangeSet 1.1009, 2003/02/27 02:41:01-03:00, m.c.p@wolk-project.de

	[PATCH] Speedup 'make dep'
	
	 During 'make dep', make spends most of its time (sometimes more
	 than 75%) uselessly analysing .hdepend. Delaying its production
	 makes 'make dep' much faster.
	 The following patch also builds .depend last, in order to make
	 the dependency information generation more resistant against
	  and other failures.


# This patch includes the following deltas:
#	           ChangeSet	1.1008  -> 1.1009 
#	            Makefile	1.204   -> 1.205
