Re: [f-cpu] optional SRB

So what ? SRB or not, it makes no difference. The OS still
has to figure out where to save the registers anyway. In one
case it will just set the SRB context block address in an SR
and let the CPU do the savin, in the other case it will have
to save registers manually.

Please note : even if the SRB is not available, the SRs 
SRB_old and SRB_new can still exist, and just be used by the
OS to emulate the SRB in a software way.
