Humm, this seems to come from:

    jchar *buf;
    Tcl_UniChar *w;

(447)	w = buf;

(501)	length = (w - buf);

My guess here is that something about the declaration of the jchar type has
changed in the JDK headers you have on your system.

An old JDK install that I have on my linux box defines jchar like so:

typedef unsigned short  jchar;

So, there would be no problem with pointer arith in this case. How
is jchar defined in your j2sdk1.4.2_09 JDK on your linux box?
Take a peek at jni.h or related include file in the JDK to find out.

The Tcl Blend source may need to be updated to deal with this
issue. I have never seen it before so I am 99% sure that
it is an issue with the way JNI types are defined in this JDK release.
