rusage overflow

[Andreas Beyer]

Hi,

I am using getrusage() to get some information on the memory usage of my 
program. Occasionally the values in the rusage structure become larger 
than the maximum long int (i.e. I get negative values).
Interpreting the overflowed long int values as positive values should 
give the correct number if memory usage is estimated by additive operations.
Is it safe to interpret the long int entries in the rusage structure as 
unsigned long int?

Thanks,
	Andreas
