That is a very strange error: I think the code is fine, but your GCC is 
confused.  I notice that GCC 3.2.2 is listed as a "known bad" version of 
GCC. It could be that 3.2.3 is also broken as well.  Is there any local 
source change you can make to that file that gets it working?  If not, I'd 
suggest upgrading to a newer GCC.  Sorry :(
