This will silence the warning, but AFAICS not fix anything.  Now you're
casting it to something explicitly unsigned, but the same size as a
pointer; but GDB tries to use the target's sign extension conventions,
and a CORE_ADDR ought to be properly sign extended on MIPS.

I think the current behavior is actually more correct despite any
warning.  Were you fixing an observed problem?
