Warning fixes:

	* bb-reorder.c (build_scope_forest): Initialize variable
	`curr_scope'.

	* calls.c (expand_call): Likewise for variables
	`save_pending_stack_adjust' and `save_stack_pointer_delta'.

	* i386.c (function_arg_advance, function_arg): Cast to avoid
	signed/unsigned warnings.

	* i386.h (MEMORY_MOVE_COST): Likewise.

	* ifcvt.c (cond_exec_process_if_block): Initialize variables
	`else_start' and `else_end'.

	* libgcc2.h (__eh_alloc, __eh_free): Prototype.

	* regrename.c (rr_replace_reg): Initialize variable `dest_subregno'.

ch:
	* Makefile.in (EXPR_H): New dependency variable.
	(actions.o, expr.o): Use EXPR_H.
	(lang.o): Depend on RTL_H and EXPR_H.

	* lang.c: Include rtl.h and expr.h.
	(lang_get_alias_set): Mark parameter with ATTRIBUTE_UNUSED.

cp:
	* decl2.c (compare_options): Don't needlessly cast away const-ness.

f:
	* com.c (lang_get_alias_set): Mark parameter with ATTRIBUTE_UNUSED.

java:
	* decl.c (create_primitive_vtable): Prototype.

	* jcf-write.c (generate_bytecode_insns): Initialize variable
