	* standard.omit: New file.
	* Makefile.in, aclocal.m4, configure: Rebuilt.
	* sources.am: New file.
	* configure.ac: Run Classpath configure script.  Moved code around
	to support.  Disable xlib AWT peers (temporarily).
	* Makefile.am (SUBDIRS): Added 'classpath'
	(JAVAC): Removed.
	(AM_CPPFLAGS): Added more -I options.
	(BOOTCLASSPATH): Simplified.
	Completely redid how sources are built.
	Include sources.am.
	* include/Makefile.am (tool_include__HEADERS): Removed jni.h.
	* include/jni.h: Removed (in Classpath).
	* scripts/classes.pl: Updated to look at built classes.
	* scripts/makemake.tcl: New file.
	* testsuite/libjava.jni/jni.exp (gcj_jni_compile_c_to_so): Added
	-I options.
	(gcj_jni_invocation_compile_c_to_binary): Likewise.

* <p>
* This implementation uses the "java.util.prefs.PreferencesFactory" system
* property to find a class that implement <code>PreferencesFactory</code>
* and initialized that class (if it has a public no arguments contructor)
* to get at the actual system or user root. If the system property is not set,

* preference node trees there are also two convenience methods to access the
* default preference node for a particular package an object is in. These are
* <code>userNodeForPackage()</code> and <code>systemNodeForPackage()</code>.
* Both methods take an Object as an argument so accessing preferences values
