Imported GNU Classpath 0.92
2006-08-14 Mark Wielaard <mark@klomp.org> 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.
