Well, I must have omitted -p when making reference copy of write.c. My 
'md5sum ./mkisofs/write.c.orig' is 9dbbf9db225d6e2fc5ef5545d8851540 and 
I bet the copy you're referring to has the same. Once again, the main 
idea behind this initial submission is to have public audit, test and 
iron the framework code. So I'd really rather discuss technical issues 
than checksums:-)
