Subject: Makefile.am: Removed java/io/Replaceable.java and
 java/io/Resolvable.java.

	* Makefile.am: Removed java/io/Replaceable.java and
	java/io/Resolvable.java.
	* Makefile.in: Rebuilt.
	* gcj/javaprims.h: Removed Replaceable and Resolvable from java.io
	namespace.
	* java/io/ObjectInputStream.java (processResolution): Fixed typo
	in method name.
	(processResolution): Handle readResolve method via reflection with
	removal of Resolvable interface.
	* java/io/ObjectOutputStream.java (writeObject): Handle writeReplace
	method via reflection with removal of Replaceable interface.
	* java/io/Replaceable.java: Removed.
	* java/io/Resolvable.java: Removed.
	* java/security/Key.java (serialVersionUID): New field.
	* java/security/Provider.java (serialVersionUID): New field.
	* java/security/interfaces/DSAPrivateKey.java (serialVersionUID):
	New field.
	* java/security/interfaces/DSAPublicKey.java (serialVersionUID):
        New field.
	* java/sql/DataTruncation.java (serialVersionUID): New field.
	* java/sql/SQLException.java (serialVersionUID): New field.
	* java/sql/SQLWarning.java (serialVersionUID): New field.
	* java/util/Date.java (serialVersionUID): New field.
	(millis): Made transient.
	(readObject): New method.
	(writeObject): New method.

Serialization mods.
Note:  The interfaces java.io.Replaceable and java.io.Resolvable were only
temporary additions to JDK 1.2 beta versions and were not included
in the JDK 1.2 final.  The Serialization spec instructs how to deal
with their methods (via reflection).
