2001-01-08  Alexandre Petit-Bianco  <apbianco@cygnus.com>

	* java-tree.h (lang_printable_name_wls): New prototype.
	* lang.c (put_decl_name): Removed dead code. Use DECL_CONTEXT
	rather than `current_class' to print type name. Don't prepend type
	names when printing constructor names.
	(lang_printable_name_wls): New function.
	* jcf-parse.c (jcf_parse_source): Pass NULL `file' argument to
	`build_expr_wfl', alway set EXPR_WFL_FILENAME_NODE.
	* parse.y (patch_method_invocation): Message tuned for constructors.
	(not_accessible_p): Grant `private' access from within
	enclosing contexts.

	* parse.y (patch_binop): Compute missing type in error situations.
