2008-06-28  Matthias Klose  <doko@ubuntu.com>

        Import GNU Classpath (classpath-0_97_2-release).

        * Regenerate class and header files.
        * Regenerate auto* files.
        * gcj/javaprims.h: Define jobjectRefType.
        * jni.cc (_Jv_JNI_GetObjectRefType): New (stub only).
        (_Jv_JNIFunctions): Initialize GetObjectRefType.
        * gnu/classpath/jdwp/VMVirtualMachine.java,
        java/security/VMSecureRandom.java: Merge from classpath.
        * HACKING: Fix typo.
        * ChangeLog-2007: New file.
        * configure.ac: Set JAVAC, pass --disable-regen-headers to classpath.

libjava/classpath/

2008-06-28  Matthias Klose  <doko@ubuntu.com>

        * m4/ac_prog_javac.m4: Disable check for JAVAC, when
        not configured with --enable-java-maintainer-mode.
        * aclocal.m4, configure: Regenerate.
        * native/jni/gstreamer-peer/Makefile.am: Do not link with
        libclasspathnative.
        * native/jni/gstreamer-peer/Makefile.in: Regenerate.
        * tools/Makefile.am, lib/Makefile.am: Use JAVAC for setting
        JCOMPILER, drop flags not understood by gcj.
