Apparently, the typeof() operator is not supported by your C compiler. 
Having relatively little experience with cross-platform programming, I 
did not notice that the typeof operator is not part of the main ANSI C 
standard. I've removed it from the sources entirely (making things 
somewhat more ugly), so your problem should be resolved with the 
following changes:

I browsed the web a little and found that IBM C should at least support 
__typeof__(e), and, with the appropriate command line options, typeof as 
well. Timo, do you know how this works and other systems that may be 
affected? Or is it a better idea to avoid typeof() in general?
