First vacation, then work, has prevented me from looking into this in  
sufficient detail earlier. Sorry for the delay.

Which platform / mac os / gcc versions was he using, and which are you  
using ? What was the compile line for the failing file in your build,  
and in his. Starting from there, we can determine in which way the  
compiler args differ, and work from there.

I would suspect it's an include / compile flags issue rather than a  
platform issue, in this specific case. If you're in a hurry to get  
octave built, I'd suggest you use another compiler variant, and see if  
that works correctly.
