Strange. I have been compiling kernels for quite a while, and not run
into this problem. I haven't ever gotten warnings, much less errors
about it.

Looking at the code, you might be correct. 'c' is the parameter which
should be printed. The question is what the compiler thinks of a parameter
and a register variable having the same name. If it double-allocates,
then there is a problem. I'm not sure what else it might do. Maybe decide
that 'c' is now a register value?

Removing 'c' from the register int declaration is a safe thing to do.
Especially as I haven't tested kernel debugging.

Take care,
