	* java/lang/System.java (setProperties): Only call init_properties()
	if properties is null.
	(getProperties): Ditto.
	(getProperty): Ditto.
	(setProperty): Call init_properties if properties are null.
	(prop_init): Remove field.
	* java/lang/natSystem.cc (init_properties): Synchronize the entire
	method. Check for null properties after synchronizing instead of
	prop_init flag. Set the properties field last for thread safety.

	* java/io/ObjectInputStream.java (ObjectInputStream): If DEBUG is set,
	test for gcj.dumpobjects property and enable object stream dumping
	if it is set.
	(dumpElement): No longer native.
	(dumpElementln): Ditto.
	(setDump): Do not define.
	* java/io/natObjectInputStream.cc (dumpElement): Removed.
	(dumpElementln): Removed.
	(setDump): Removed.

2000-11-24  Bryce McKinlay  <bryce@albatross.co.nz>

	* configure: Rebuilt.
	* Makefile.in: Rebuilt.
	* Makefile.am (built_java_source_files): Add Configuration.java.
	* configure.in: Add Configuration.java to CONFIG_FILES. Set
	LIBGCJDEBUG substitution if --enable-libgcj-debug is specified.
	Create `gnu' directory in the build tree.
	* gnu/classpath/Configuration.java.in: New file.
