* Makefile.in (VERSION): Bump to 4.5.6.

* coffread.c (coff_end_symtab):  Cast 2nd arg of complain() to
	correct type.
	* defs.h (NORETURN):  Define away for Lucid compiler.
	* remote.c (remote_timer, remote_interrupt):  Signal handlers
	take one int arg.
	* ser-termios.c (serial_write, serial_close):  Return whatever
	value the write/close call returns, rather than falling off end.
	* inferior.h (PTRACE_ARG3_TYPE):  Third arg to ptrace is int on
	more systems than it is "char *".  Define PTRACE_ARG3_TYPE to
	default to int.
	* infptrace.c, hppabsd-xdep.c, hppahpux-xdep.c, i386-xdep.c,
	inferior.h (call_ptrace):  Use PTRACE_ARG3_TYPE to declare type
	of third arg.
	* a68v-xdep.c, arm-xdep.c, convex-xdep.c, hp300ux-xdep.c, infrun.c,
	m88k-xdep.c, mach386-xdep.c, mips-xdep.c, os68k-xdep.c, pyr-tdep.c,
