This is that code that is meant to check for that case, from tcljava.m4.

        # Blackdown JDK 1.1 for Linux (this one can get a little wacky)

        F=README.linux
        if test "x$ac_java_jvm_jni_lib_flags" = "x" &&
            test -f $ac_java_jvm_dir/$F ; then
            # Figure out if it is 1.1.8 and not 1.1.7
            AC_GREP_FILE([JDK 1.1.8], $ac_java_jvm_dir/$F, IS118=1)

            F=lib/`uname --machine`/native_threads/libjava.so
            AC_MSG_LOG([Looking for $ac_java_jvm_dir/$F], 1)
            if test -f $ac_java_jvm_dir/$F ; then
                AC_MSG_LOG([Found $ac_java_jvm_dir/$F], 1)
                D=`dirname $ac_java_jvm_dir/$F`
                ac_java_jvm_jni_lib_runtime_path=$D
                ac_java_jvm_jni_lib_flags="-lpthread -L$D -ljava"


On my system.

% uname --machine
i686

Is there no symlink for i686 -> i386 on that box?
Is this a Sun JVM on Linux or a blackdown one?

Well, the patch for tcljava.m4 is what we need in the long run.
I just did an update from the autoconf CVS and it looks like
something related the AC_FD_LOG macro was changed. I just
checked in a change that fixes that problem. It should
work with the CVS version of autoconf now.
