 Of course after.
 
 The problem is that printf is called with a format string
 denoting a 'long' value, but gets passed a parameter that is
 'time_t'. This works fine unless 'time_t' is larger than 'long'.
 
 Casting the parameters to 'long' helps unless the value
 printed doesn't fit into a 'long' (i.e. rusage is more than
 2^31 seconds == 68 years CPU time).
 
 If you want to support larger rusage values, the format string
 needs to be adapted. But that might have portability issues for
 tcsh.
