[Etherboot-developers] tidy ups

[<ke...@us...>]

I've just checked in a bunch of tidy ups to source files to remove
unused variable warnings. I've also got rid of line that was causing the
shell to barf on a FP number in arch/i386/Makefile.

Does anybody know how to declare the unused attribute on function
parameters, and just as important, does it work with older gcc versions
like 2.95?

Does anybody know how to get rid of these warnings? I assume this is
because they are now predeclared in gcc 3.x?
