Let me be the first in a long line of people commenting on this one.
(It's 8:30 am pdt, june 27).

It is not the business of the compiler (any compiler?) to interpret the
data present at an address passed at run-time to a subroutine, and 
thereby to determine that certain functions called by that subroutine 
(in this case, formatters) won't actually actually be needed, and so
on to indicate somehow to the linker that those references can be
left unresolved.  I guess that what I am saying is that you should buy
an amiga and program a whole lot and learn a whole lot.

Also, I am told that the printf in the kernel (kprintf and the stuff it
uses) don't handle floating point.  The intent of those routines is 
for debugging use.  I think I am in favor of building printf right
into your system, but that wasn't the intent of kprintf, as I understand it.

But then again, poof:  I may be wrong.
