Re: [PATCH] libjava/classpath/native/jni/java-lang/java_lang_VMProcess.c: Be sure 'errbuf' always be zero terminated.

I guess, I find the root cause:

In "gcc/libjava/configure", "--disable-core-jni" is hardcoded manually
for classpath with FIXME, then all related trying are useless. For me,
if have parameter "--enable-core-jni", need skip "--disable-core-jni".

The related information in gcc/libjava/configure:

 6820 # Set up to configure Classpath.
 6821 # FIXME: no supported way to pass args in autoconf.
 6822 # Disable tool wrappers to avoid ltdl.h configure check.
 6823 ac_configure_args="$ac_configure_args --disable-tool-wrappers"
 6824 ac_configure_args="$ac_configure_args --disable-load-library"
 6825 ac_configure_args="$ac_configure_args --${LIBGCJDEBUG}-debug"
 6826 ac_configure_args="$ac_configure_args --enable-default-toolkit=$TOOLKIT"
 6827 dir1=`cd $srcdir && pwd`
 6828 dir2=`pwd`
 6829 ac_configure_args="$ac_configure_args --with-vm-classes=$dir1:$dir2"
 6830 ac_configure_args="$ac_configure_args --disable-core-jni"
 6831 ac_configure_args="$ac_configure_args --disable-examples"
 6832 ac_configure_args="$ac_configure_args --with-glibj=build"
