Well, I've been talking about doing this for so long that I feel I must take this as a challenge... I will give it a shot.
All that I've done so far is to look at config.gcc and shudder at what a mess it would be to separate libgcc. But really it is not necessary, and one could keep #includ'ing tm.h from libgcc. Which makes me shudder too, but so what.
Try doing it without bootstrap for now, toplevel bootstrap is quite near (first I want to apply the fixes for the Ada problems).
