SUN4 / SUNOS4.0 / C Compiler Problems

The optimizer for the sparc is known to be broken, so avoid using it.  I
couldn't get X Windows 11.3 running until I removed the -O flag from the
Makefiles.

the "Watchdog Reset" problem with the 4/110 is a hardware bug for which
Sun has a software workaround (a new trap.o kernel module). This will
Prevent the system from crashing.

You didn't expect this to work, did you?  How does the function know what
offset to generate for argv[1]?  It has to know the second dimension of
the matrix in order to generate right offsets.

Try declaring the argument in foo() as "char argv[][BUFSIZ]".
