* Makefile.in (varasm.o): Depend on dbxout.h.
(cse.o): Depend on toplev.h and output.h.
(gcse.o): Depend on output.h.
* mips.c: Include system.h and toplev.h and remove redundant code.
Include output.h after tree.h so all its prototypes get activated.
* mips.md (table_jump): Remove unused variable `dest'.
* sparc.h: Add prototype for `v8plus_regcmp_op'.
* crtstuff.c (fini_dummy, init_dummy): Mark function definitions
with __attribute__ ((__unused__)).
(__frame_dummy): Provide prototype before use, wrap it with
EH_FRAME_SECTION_ASM_OP.
* cse.c: Move inclusion of <setjmp.h> above local headers.
Include toplev.h and output.h.
* dbxout.h: Add prototype for `dbxout_begin_function'.
* final.c (final_scan_insn): Wrap variable `max_skip' in macro
ASM_OUTPUT_MAX_SKIP_ALIGN.
* gcse.c: Include system.h and output.h.
(dump_cuid_table, dump_rd_table, dump_cprop_data, dump_pre_data):
Make extern instead of static.
(compute_can_copy): Only declare variables `reg' and `insn' when
AVOID_CCMODE_COPIES is not defined.
(record_set_info): Mark parameter `setter' with ATTRIBUTE_UNUSED.
(hash_scan_clobber): Likewise for `x' and `insn'.
(hash_scan_call): Likewise.
(record_last_set_info): Likewise for `setter'.
(mark_call): Likewise for `pat'.
(pre_insert_insn): Wrap variable `note' in macro HAVE_cc0.
* libgcc2.c (__bb_init_prg): Replace bzero with memset and fix the
length parameter so that it multiplies the number of elements by
the sizeof(element).
* output.h: Add prototype for `weak_finish'.
* recog.h: Likewise for `validate_replace_src'.
* rtl.h: Likewise for `optimize_save_area_alloca',
`fix_sched_param', `purge_addressof', `gcse_main',
`regmove_optimize', `dbr_schedule', `branch_prob' and
`end_branch_prob'.
* toplev.h: Likewise for `set_float_handler' and
`output_quoted_string'.
* varasm.c: Include dbxout.h.
