It won't build anymore

Adding to xrabohrok said, printf doesn't seem to work outside of the default routines. Anything that isn't sent directly through the function that loops the code through the micro processor won't print anything. It seems to give those errors too.

Sounds like you have the same problem addressed in this thread. Check the lines right before "#include <stdio.h>", you've probably got a random letter right before it.

By the way, try searching next time... A search for "stdio.h syntax error" got the thread I linked to above
