I've tried downloading libcxxabi (using svn), but the script given in 
libcxxabi/lib/buildit does not produce an
error-free compilation. Please find attached the build log for libcxxabi 
(it's only2.1kb). It needs _Unwind_Exception.
Where would that be? And, of course, maybe libcxxabi doesn't work yet on 
Linux. :-(
