       Imported GNU Classpath 0.92
       * HACKING: Add more importing hints. Update automake version
       requirement.

       * configure.ac (gconf-peer): New enable AC argument.
       Add --disable-gconf-peer and --enable-default-preferences-peer
       to classpath configure when gconf is disabled.
       * scripts/makemake.tcl: Set gnu/java/util/prefs/gconf and
       gnu/java/awt/dnd/peer/gtk to bc. Classify
       gnu/java/security/Configuration.java as generated source file.

       * gnu/java/lang/management/VMGarbageCollectorMXBeanImpl.java,
       gnu/java/lang/management/VMMemoryPoolMXBeanImpl.java,
       gnu/java/lang/management/VMClassLoadingMXBeanImpl.java,
       gnu/java/lang/management/VMRuntimeMXBeanImpl.java,
       gnu/java/lang/management/VMMemoryManagerMXBeanImpl.java,
       gnu/java/lang/management/VMThreadMXBeanImpl.java,
       gnu/java/lang/management/VMMemoryMXBeanImpl.java,
       gnu/java/lang/management/VMCompilationMXBeanImpl.java: New VM stub
       classes.
       * java/lang/management/VMManagementFactory.java: Likewise.
       * java/net/VMURLConnection.java: Likewise.
       * gnu/java/nio/VMChannel.java: Likewise.

       * java/lang/Thread.java (getState): Add stub implementation.
       * java/lang/Class.java (isEnum): Likewise.
       * java/lang/Class.h (isEnum): Likewise.

       * gnu/awt/xlib/XToolkit.java (getClasspathTextLayoutPeer): Removed.

       * javax/naming/spi/NamingManager.java: New override for StackWalker
       functionality.

       * configure, sources.am, Makefile.in, gcj/Makefile.in,
       include/Makefile.in, testsuite/Makefile.in: Regenerated.
