setjmp/longjmp on mips/ultrix4

I'm now trying to port Kaffe to mips/ultrix4.2. But the jmp_buf structure
on this OS is something strange.

The problem I have right now is, if I change saved stack pointer in
jmp_buf and call longjmp (which is used to make threads), it failed
with 'longjmp botch...'.

Unfortunately the actual longjmp is handled by 'sigreturn' system
call, and there are no way to trace down.

If someone has idea how to tackle this problem, I am fully appreciated.

# For the time being, I try to use glibc...
