What I found was that sun 3.2 does you a real "favor" with its new csh.
If you look at the imagen filters, you find that  they are really one
csh script with 33 hardlinks (different names to it).  /usr/lib/lpd is
an suid program and the new csh will not let you exec a csh script from 
an suid program without your giving the -b flag when you crank it up.
We found this out the hard way (although it is documented on the csh
man page).  This "favor" will probably break other things too.


Here is the fix.  Change the top line of the shell script from

#!/bin/csh -f

to

#!/bin/csh -bf
