Hello,

You are correct; I am using GNU make, err, rather, trying to, at least.
Found a typo that fixed part of the problem: $(addprefix, PREFIX, ITEM)
should be $(addprefix PREFIX, ITEM). Note that there is no comma after
'addprefix'. 

This particular Makefile seems to be horribly broken. So I think I might
as well start over. Further reading shows that the 'vpath' directive
should be used in this case, or '.PATH' for BSD make. 

Thanks for the suggestion at least...

-Andrew
