thanks for the patch, I've checked it in.

I've checked in a fix into the CVS. thanks for reporting it.

it seems that divjava fails because long remainder is broken on powerpc-linux.
Could you try out the following C program, and report back what it prints out:

#include <stdio.h>
#include <limits.h>
#define T long
#ifndef LONG_MIN
# define LONG_MIN ((((unsigned T)(~(T)0))>>1)+1)
T foo(T i, T j);
int main() { int tmp = foo(LONG_MIN, -1l) == 0; printf ("%d\n", tmp); return
T foo(T i, T j) { return i % j; }
