Hi,

sorry for long reply time.

Is casting buffer to char* enough to get away with the warning? I think 
I would prefer it to be done this way if it works.

I'm also not sure if this warning is useful. I don't see anything wrong 
in computing the pointer as long as it's not accessed. I guess it can't 
be disabled without also disabling some useful warnings?

Thanks,
Piotr
