	* gnu/java/rmi/rmic/Compile_gcj.java (COMPILER_ARGS): New private
	constant.
	(computeArguments): use computeTypicalArguments.

	* gnu/java/rmi/rmic/Makefile.am (EXTRA_DIST): Add Compile_kjc.java,
	Compile_jikes.java and RMICException.java.
	* gnu/java/rmi/rmic/Compile_kjc.java: New file.
	* gnu/java/rmi/rmic/Compile_jikes.java: Likewise.
	* gnu/java/rmi/rmic/RMICException.java: Likewise.

	* gnu/java/rmi/rmic/Compiler.java (getDestination): New method.

	* gnu/java/rmi/rmic/CompilerProcess.java: Import java.io.InputStream.
	(computeTypicalArguments): New method.
	(compile): Print compiler output to System.out. Collect compiler
	error output and use it in exception message.

	* gnu/java/rmi/rmic/RMIC.java: Import java.util.Set.
	(destination): Initialize to null.
	(run): Replace file separator with '.' when processing class.
	(processClass): Replace '.' with file separator when compiling
	classes.
	(findClass): Use SystemClassLoader to load class.
	(generateStub): Use full class name for generated stub, that puts
	it in right path.  Replace '.' with file separator when generating
	stub file name. Write just the stub class name without package
	information as class name, and constructor name. Write only
	interface names for interfaces extending java.rmi.Remote as
	implemented.
	(generateSkel): Use full class name for generated skel, that puts
	it in right path.  Replace '.' with file separator when generating
	stub file name. Write just the stub class name without package
	information as class name.

	* Makefile.am (rmi_java_source_files):
	Added gnu/java/rmi/rmic/Compile_kjc.java,
	gnu/java/rmi/rmic/Compile_jikes.java and
	gnu/java/rmi/rmic/RMICException.java
	* Makefile.in: Regenerated.
