After surfing through many sites, and (sadly) even more 404s I have been unable to find a definitive list of gcc, binutils, BrickOS etc. versions and patches that I should and could be using. Presumably everybody here has up to date versions of all (...) (15 years ago, 13-Apr-09, to lugnet.robotics.rcx.legos)
