Hello again, I completed the bootstrap process ignoring the stage 2 compiler warning. The stage 3 compiler generates the same warnings, but it does create good executable code. I am currently running a make check-gcc that will take many hours on a 68040. I am completely baffled by what could make gcc generate the warnings below for all declared functions, including the built-ins. I would be very grateful for any suggestions or ideas. Thank you!
