Hi

Sure I can do that! I have saved some patches just to be able to use
this new feature.
But should I submit everything as one patch then?
Or is there some kind of dependency thing I can use...

I have also e-mailed with Dan about this, he pointed out the same as
some of my tests indicate that strzcpy maybe just should use strncpy
and add a null character instead because strncpy is optimized
depending on the hardware it runs on.
What do you think about that?


Kind regards
