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,
