In gcc/:

	* bitmap.c (bitmap_element_allocate): Remove unused parameter;
	change callers accordingly.
	* cplus-dem.c (arm_special): Remove unused parameter work in prototype
	and definition; change all callers accordingly.
	* except.c (init_eh): Avoid assignment of unused return value of
	build_pointer_type; cast it to void, instead, and remove unused
	variable type.
	* gcc.c (lang_specific_driver): Define prototype only #ifdef
	LANG_SPECIFIC_DRIVER.
	(temp_names): Define only #ifdef MKTEMP_EACH_FILE.
	* genoutput.c (output_epilogue): Initialize next_name to 0.
	* real.c (efrexp): #if 0 prototype and function definition.
	(eremain): Likewise.
	(uditoe): Likewise.
	(ditoe): Likewise.
	(etoudi): Likewise.
	(etodi): Likewise.
	(esqrt): Likewise.
	* reload.c (push_secondary_reload): Define prototype only
	#ifdef HAVE_SECONDARY_RELOADS.
	* varasm.c (assemble_static_space): Define rounded only
	#ifndef ASM_OUTPUT_ALIGNED_LOCAL.
In gcc/cp/:
	* call.c (default_parm_conversions): Remove prototype definition.
	(build_method_call): Remove unused variable result.
	* cvt.c (ocp_convert): Remove unused variable conversion.
	* decl2.c (ambiguous_decl): Add explicit parameter definition for name.
	* except.c (do_unwind): #if 0 definition of unused variables fcall
	and next_pc.
	* expr.c (extract_scalar_init): #if 0 prototype and function definition.
	* init.c (expand_aggr_init_1): Remove unused variable init_type.
	(build_new_1): Remove unused variable t.
	* pt.c (instantiate_class_template): Remove unused variable newtag;
	cast called function return value to void.
	(do_decl_instantiation): Remove unused variables name and fn.
	* tree.c (get_type_decl): Add default return to shut up compiler from
	complaining control reaches end of non-void function.
	* typeck.c (build_x_conditional_expr): Remove unused variable rval.
