Jim Kingdon f46ffb9ebd More gcc lint:
* exec.c (ignore): Return 0.
	* stack.c (return_command): Fetch lazy value directly, not via
	VALUE_CONTENTS, to avoid "value computed is not used".
	* inflow.c (new_tty): Move osigttou inside #if.

	* remote.c (remote_fetch_registers): If remote reply is short, just
	note that fact and keep going (reading extra registers as all bits 0).
	(remote_store_registers): Send number of registers that were found
	by remote_fetch_registers.
	* m68k-tdep.c, config/m68k/tm-m68k.h, config/m68k/tm-*.h: Remove
	HAVE_68881.  Define CANNOT_STORE_REGISTER if ptrace() can't write
	floating registers.
	* config/m68k/{tm-m68k-nofp.h,m68k-nofp.mt,tm-m68k-fp.h,m68k-fp.mt}:
	Remove, replaced by {tm-m68k-em.h,m68k-em.mt}.
	* Makefile.in, configure.in: Change accordingly.
