Well... Someone said of his code that the only reason it is bug-free is because it scares bugs away. Large amounts of pointer arithmetic. Religious checks (heck, he even checks if printf (not fprintf) succeeds or not), and... odd (not sure if it's the right word. maybe insane is better) macros. Plenty of one letter variables.

Misunderstand me correctly, he writes solid software. He's not just a guy I would like to work with :)
