It's not that I want to make assumptions about types but printf forces me to 
do so. Your example above works as long as it doesn't hit a plattform 
where "long" is defined as 64 bit type (e.g. Alpha, AIX). On these 
plattforms, it will fail miserably.

On the other hand I don't know if there is a way out of this problem when two 
libraries define CS_INT different. For the moment people using the sybase 
backend in combination with FreeTDS have to live with this warnings.
