Thanks for the patch, I did add it. The problem regarding the exception 
handling seems to be gone, the compilers/library that come with the system 
seem to be better in that regard. With the patch, it drops the number of 
unexpected failures from 8 to 2 on sparc64 and i386 (gcc-3.3). However, on 
sparc it now produces even more errors, see appended log files. It now whines 
about unused parameters.
