* d30v.h: Fix declaration of reg_name_cnt. * d10v.h: Fix declaration of d10v_reg_name_cnt. * arc.h: Add prototypes from opcodes/arc-opc.c. For opcodes: * tic54x-dis.c: Add unused attributes where needed. * z8k-dis.c (output_instr): Add unused attribute. * h8300-dis.c: Add missing prototypes. (bfd_h8_disassemble): Make static. * cris-dis.c: Add missing prototype. * h8500-dis.c: Likewise. * m68hc11-dis.c: Likewise. * pj-dis.c: Likewise. * tic54x-dis.c: Likewise. * v850-dis.c: Likewise. * vax-dis.c: Likewise. * w65-dis.c: Likewise. * z8k-dis.c: Likewise. * d10v-dis.c: Add missing prototype. (dis_long): Remove unused variable. (dis_2_short): Likewise. * sh-dis.c: Add missing prototypes. * v850-opc.c: Likewise. Add unused attributes where needed. * ns32k-dis.c: Add missing prototypes. (bit_extract_simple): Remove unused variable.
