I added your suggested changes to my Makefile, where it will now compile and
link successfully. However when I try to boot the application I get the
following error:
"Error 7: Loading below 1MB is not supported"

Now I googled this and found that this error message can be reported from GRUB,
which I do use, but it was never reported previously when booting the RTEMS
sample applications with GRUB. Therefore I don't think it is totally isolated
to GRUB, but I don't know how to fix it, so do you or anyone else have any
reason why you think this may be occuring?

I was going to try to use your OMK template, however I was unable to get GNU
make-3.81 on and it is going to be a long task to get the latest version on my
developement system. So I would prefer to try and get it working via the first
solution (the simple makefile), where if all else fails I will need to update
my developement system for the use of the OMK template.

If anyone else has any feedback I would greatly apprieciate it.
