Warning: mksh has not yet been ported to or tested on your
operating system 'SINIX-Z'; it may or may not work.

If you can provide a shell account to the developer, this
may improve; please drop us a success or failure notice or
even send patches for the remaining issues, or, at the very
least, complete logs (Build.sh + test.sh) will help.
