	* check-init.c (flags.h): Include
	(check_init): Don't report uninitialized static class
	initialization flags, don't free bit index when doing static class
	initialization optimization.
	(check_for_initialization): Return type changed to `unsigned int.'
	(attach_initialized_static_class): New function.
	* class.c (add_method_1): Create the initialized static class
	table if necessary.
	(finish_class): Always emit deferred inline methods.
	* decl.c (emit_init_test_initialization): Moved to expr.c
	(complete_start_java_method): Don't traverse
	DECL_FUNCTION_INIT_TEST_TABLE.
	(lang_mark_tree): Mark hash tables in function decls.
	* expr.c (emit_init_test_initialization): Moved from decl.c.
	(build_class_init): Create LAG_DECL_SPECIFIC for the static class
	initialization flag, set DECL_CONTEXT and
	LOCAL_CLASS_INITIALIZATION_FLAG.
	(java_lang_expand_expr): Emit initialization code for static class
	initialized flags when entering block, if necessary.
	* gcj.texi (-fno-optimize-static-class-initialization): Documented.
	* java-tree.h (flag_optimize_sci): New global variable declaration.
	(DECL_FUNCTION_INITIALIZED_CLASS_TABLE): New macro.
	(DECL_FUNCTION_STATIC_METHOD_INVOCATION_COMPOUND): Likewise.
	(LOCAL_FINAL_P): Fixed typo in comment.
	(FINAL_VARIABLE_P): Likewise.
	(LOCAL_CLASS_INITIALIZATIO_FLAG): New macro.
	(LOCAL_CLASS_INITIALIZATIO_FLAG_P): Likewise.
	(struct lang_decl): New fields `ict', `smic' and `cif.'
	(check_for_initialization): New returned value for global.
	(attach_initialized_static_class): New global function.
	(STATIC_CLASS_INIT_OPT_P): New macro.
	* lang-options.h (-fno-optimize-static-class-initialization): New flag.
	* lang.c (java_decode_option): Handle
	`-fno-optimize-static-class-initialization'
	* parse.y (start_complete_expand_method): New function.
	(java_expand_method_bodies): Likewise.
	(attach_init_test_initialization_flags): Likewise.
	(adjust_init_test_initialization): Likewise.
	(emit_test_initialization): Likewise.
	(java_complete_expand_methods): Nullify abstract and native method
	bodies.
	(java_complete_expand_method): New locals `fbody', `block_body'
	and `exception_copy.' Reorganized: directly return on empty method
	bodies, call `start_complete_expand_method', remember definitely
	initialized static class in function, don't expand method bodies.
	(java_expand_classes): Call `java_expand_method_bodies' before
	`finish_class' when compiling to native.
	(resolve_expression_name): Use `orig' after building outer class
	field access.
	(patch_invoke): Remember static method invokations.
