GCC does still have a pdp11 backend today. It doesn't seem to be very actively maintained, and how well it works nowadays is possibly another question, but it should at least be buildable. > I assume they also removed the switch for K&R mode. I'm not sure there ever was such a switch. If there was, it was removed a long time ago. "-std=c90" still works and should accept some, maybe most, K&R code. As others have noted, GCC has no option to accept pre-K&R C, though I suspect it would probably not be all that hard to write some sort of preprocessor to convert such code to either K&R or C90 dialect. p.
