Oops. I will not post again until your second point is resolved.

Did wonder why simulator signals needed to equated to the host signals. I am still not 
clear why the code is like this.

I see what you mean.

The TARGET_SIGNAL_* shows up in the ppc, d10v, and arm sims. The host type SIG* such as 
SIGBUS appear to be in most of the sims.

Is the solution to change sim-signal.c to use TARGET_SIGNAL_* and then change the effected 
sim files to SIM_SIG* ?
