        * alpha-osf1-tdep.c (alpha_osf1_init_abi): Unfortunately,
        procfs appears to be broken when debugging on multi-processor
        machines. So enable software single stepping in order to avoid
        using the procfs interface to do next/step operations, using
        internal breakpoints instead.

Unless Jason Thorpe objects, this part of the change is approved. The other alternative would be to select this based on the OS.

Software single step needs to be moved to the target vector.

I need to look some more at the other change. !*&(*!@(^#* DECR_PC_AFTER_BREAK.
