@mtdudek Thanks for picking this up. There should be no external library calls in the benchmark.

I'd rather just remove this code. The danger with #define is that users will define them on the command line and we'll get invalid results. Are you happy to make this change?

Added @PaoloS02 as a second reviewer.

I've removed printfs from benchmarks' bodies.
