For those who are still trying to get the threading system of Kaffe 0.10.0
to run on a new architecture:

On a UNIX-like system, the following program prints out the correct
#define for SP_OFFSET.

Maybe we can include this in the configure process?

-- sp_offset.c --
#include <setjmp.h>
#include <assert.h>
#include <stdio.h>
#include <sys/wait.h>

int  sp_offset;
char new_stack[4096];

static void
check()
{
    char x;
    exit (&x < new_stack || &new_stack[sizeof new_stack] < &x);
}

main(int ac, char *av[])
{
    int  stat;
    pid_t child;
    jmp_buf buf;

    for (; sp_offset < sizeof (buf) / sizeof (void *); sp_offset++) {

	if ((child = fork()) == 0) {	/* child */

	    if (setjmp(buf)) 
		check();

	    *(void **)(((void **)buf) + sp_offset) = 
		    &new_stack[(sizeof new_stack)/2];
	    longjmp(buf, 1);
	    exit(-1);

	} else {	/* parent */

	    assert(child == wait(&stat));

	    if (WEXITSTATUS(stat) == 0 && !WIFSIGNALED(stat))
		printf("#define\tSP_OFFSET\t%d\n", sp_offset);
	}
    }
}
