	* decl.c (long_zero_node, float_zero_node, double_zero_node): New
 	global variables, initialized.
	* java-tree.h (long_zero_node, float_zero_node, double_zero_node):
 	Declared new global variables.
	* lex.c (java_lex): Return long_zero_node, float_zero_node,
 	double_zero_node, integer_zero_node upon direct matching.
	* parse.y (purify_type_name): Added function prototype.
	(duplicate_declaration_error_p): Consider new_type as potentially
 	being a incomplete type. Use purify_type_name on type string.
	(method_header): saved_type: unused variable removed. Don't figure
 	return type if method name is invalid.
	(java_complete_tree): Set CAN_COMPLETE_NORMALLY after `node' was
 	processed by patch_unaryop.
	(patch_unaryop): Fixed typo in comment. Re-convert pre/post
 	increment/decrement node into its original type after binary
 	numeric promotion on its operands.
Fixes a bug occuring when an error occurs in constructor
declaration. Fixes a bug on ++/-- operators on non integer operands.
