Diane,
thanks for trying, at least I know what kind
of output I have to expect from depend.
But the situation is still the same:
depend does create the .dep files correctly.
but it doesn't delete files.
I also checked the time stamps,
-rw-r--r--   1 justin   lbri        10883 May 16 14:43 ResultTable.java
-rw-r--r--   1 justin   lbri         1407 May 16 10:36
ResultTable$ListComparator.class
-rw-r--r--   1 justin   lbri         6602 May 16 11:34 ResultTable.class

-rw-r--r--   1 justin   lbri         1840 May 16 14:46 Tracer.java
-rw-r--r--   1 justin   lbri         1438 May 16 10:19 Tracer.class
because we had the problem before that the fileserver and the system
the jobs are running have slightly out of sync. So for example 'make' would
complain that
it's makefile was created in the future. But not this time, I checked it!!!
I'm going to try it on other maschines, including windoze.

Cheers

Justinus
