* hp300ux-nat.c: Cast second arg to supply_register calls.

Browse Source 
(_initialize_kernel_u_addr, getpagesize): New functions.
	(store_inferior_register_1): Change arg name from value to val.
	(fetch_core_registers): Make arg core_reg_size unsigned.
	Pass 5 args to ptrace.
	* config/m68k/xm-hp300hpux.h: Define FIVE_ARG_PTRACE.
	Remove KERNEL_U_ADDR stuff.
	* infptrace.c [FIVE_ARG_PTRACE]: Pass 5th arg to ptrace.
	* config/m68k/hp300hpux.m{t,h}:
	Move exec.o from NATDEPFILES to TDEPFILES
	* config/m68k/hp300hpux.mt: Mention GAS requirement.  Remove
	hp-include stuff.  Add m68k-tdep.o to TDEPFILES.
