I should have said I was using mingw-builds 4.8.2.
I assume this is the latest compiler I should use, yes?
I tried it with and without memset().
I had to rework my code to make an example you might be able to compile.
hmmph. I think as long as I was working on that prime numbers project, it was
failing. things were going wrong all over. maybe I wasn't supposed to do that
project. :-/
