dc benchmark much too short

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Running the dc benchmark

The command dc < dc.dat is computed very fast on modern computers, less than a 
millisecond. So the dc benchmark is benchmarking fork and exec instead 
(looper.c).

It is easy to change, by increasing the precision of sqrt(2) calculation.

Thanks
