Yes, but your message could be interpreted as suggesting that this person, who was clearly calling Makefiles in subdirectories directly rather than using the top-level Makefile, should have first compiled the new compiler directly, and then compile the new RTL using this new compiler. Given the amazingly creative ways in which people manage to keep trying to compile FPC in unsupported ways, I did not want anyone to get the idea that this would be a good approach.
