Removed warnings by assigning to bool

[crozhon]

There's no mention in the style guide of whether the !!value or value != 0 syntax is preferred for casts to bool. I asked around on IRC and value != 0 seems to be preferred.

LGTM

Looks good if you parenthesize the var != 0 conditions.

Thanks for going through the trouble of fixing these warnings though. You make my future workload a little lighter. I appreciate it :)

Should be all set. And it's no problem. It gives me a chance to get familiar with the code and maybe fix a real issue somewhere down the road.
