(inf_ptrace_xfer_partial): Use "uintptr_t" instead of "long" as
	intermediate type when casting CORE_ADDR to PTRACE_TYPE_ARG3.
	(inf_ptrace_fetch_register): Add intermediate cast to "uintptr_t"
	before casting CORE_ADDR to PTRACE_TYPE_ARG3.
	(inf_ptrace_store_register): Likewise.
	* Makefile.in (inf-ptrace.o): Update dependencies.
