           Summary: The boot loader forth does not understand 'outb' on

'outb' amd64 patch

'outb (port char --)', according to loader(8), writes a value to a port.
However, it only does so on the i386 platform (and possibly non-x86 platforms,
but this is outside of the scope of this report), ihe 'outb' word is not
recognised on amd64.

One would expect this would also work on amd64.

A patch is supplied which enables 'outb' on amd64 also. Note that after the
patch is applied, i386/sysdep.c and amd64/sysdep.c have the same contents.
