 Makefile.in (sparcbsd-nat.o, sparc64fbsd-nat.o, sparc64-tdep.o,
 sparc64fbsd-tdep.o): New dependencies. (SFILES): Add sparcbsd-nat.c,
 sparc64fbsd-nat.c, sparc64-tdep.c and sparc64fbsd-tdep.c. (sparc64_tdep_h,
 sparcbsd_nat_h): New variables. * config/sparc/fbsd.mh: Remove copyright
 notice. (NATDEPFILES): Remove sparc-nat.o, add sparc64fbsd-nat.o and
 sparcbsd-nat.o. * config/sparc/fbsd.mt: Remove copyright notice. (TDEPFILES):
 Remove sparc-tdep.o, solib.o solib-svr4.o, solib-legacy.o.  Add
 sparc64-tdep.o and sparc64fbsd-tdep.o. * config/sparc/nm-fbsd.h: Don't
 include "elf/common.h". (SVR4_SHARED_LIBS, PTRACE_GETREGS, PTRACE_SETREGS,
 PTRACE_GETFPREGS, PTRACE_SETFPREGS, GDB_GREGSET_T, GDB_FPREGSET_T, regs,
 r_g1, r_ps, r_pc, r_npc, r_y, FPU_FSR_TYPE, fp_status, fpu, fpu_regs, fp_fr,
