* 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.
* stabsread.c (define_symbol): Make the caddr_t hack apply to `function
returning foo' as well as `pointer to foo'.
* remote.c [REMOTE_BREAKPOINT]: Use for breakpoint insn if defined.
* config/m68k/tm-m68k.h: Define it.
* mem-break.c, breakpoint.c: Improve comments.
