Hello,

looking at the "supported system" list for gcc, I see "This port is  
very preliminary and has many known bugs.  We hope to have a  
higher-quality port for this machine soon." Not very encouraging.  
Still, if you want to pursue this bug, I suggest that you try out the  
latest gcc cvs and see how it fairs. Neil Booth (our cpp maintainer)  
has been doing a lot of work to make cpp more robust wrt character sets  
and the like, and I suspect that if you try out mainline, and have  
feedback to give him, he might be able to fix the issue. In any case,  
3.2 branch is dead at this point, so you'll have to try a newer version  
at some point anyway. Cheers,

Dara
