Re: make


We disable Mcafee for the builds as it adds to much overhead.
I am looking in Task Manager to start with to see the utilization.
I see no difference from using make -j x (where x is the number of 
processors).and make without the -j switch.
By using make -j you can take advantage of parallel executions.
Please let me know if I'm invoking it incorrectly.
