Hi, I am trying to build rtems-libbsd from the latest source for pc386 bsp, but I am getting errors:

It looks like the pc386 BSP defines breakpoint() and this is clashing. I think it is simpler for RTEMS to not use names that could clash. I suggest raising an MR on the pc386 BSP to change it’s name to something that would not clash, for example rtems_p386_breakpoint()?
While I have fixed that conflict, I found another one:

I will try to fix this.
