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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@137223 138bc75d-0d04-0410-961f-82ee72b054a4
