This is not because the debug code is needed, but because the link directive
generated by the compiler is wrong when using -d: The libraries
'-lsocket -lnsl' are missing before '-lm -lc'.
This error was fixed in release 4.0.1 of the Mjolner BETA System.

You can work around the error by compiling with -p (preserves job file),
add '-lsocket -lnsl' before '-lm' in sun4s/main..job, and then execute
sun4s/main..job.

Sincerely,
