 Thanks, who would have thought about di-graphs ;) ? I hesitated a while
 to submit a bug report, because I thought somebody else surely must have
 caught this before. I finally did it since the Kai compiler compiled the
 code without complaints, but it turns out that it has digraphs disabled
 in the default mode and you have to give some --strict option to enable
 them.
 
 Maybe this can go into that 'bugs which aren't really bugs' web page you
 got ? It might give people a clue when they run into similar problems.
 
 cheers, Reiner
