Problem with AIX-4.1 + patch

  On an AIX 4.1

Stop.

The offending assembly instructions are in reschedule :

3284                bl 1f
3285                nop
3286                nop
3287                nop
3288                nop
3289        1:      nop
3290                nop
3291                nop
3292                nop
3293                mflr 27
3294                addi 27, 27, 2f-1b

3335                nop
3336        2:      nop
3337                nop

I have noticed that all local addresses were L..xxx .
Replacing in the 1, 1b and 1f identifier by L..999 and 
2 and 2b by L..1000 , running the assembler by hand

as -u -mpwr -o thread.o thread.s

and finishing the make the normal way produced a valid
(seems so) kaffe interpreter (I was able to compile without
problems jigsaw + amaya classes).

The patch follows at the end of the mail. Note that gcc
calls the native as assembler in my setup with the flags
-mpwr and hence for the original POWER chip set present
in the RS6000 line of machines. Seems that this assembler
don't understand labels beginning with numbers. I hope that
replacing them with L..xxx labels won't broke on the others
PPC environments.
