No, actually you don’t. The environment block is odd, in that you can 
access it via getenv(3) and friends, without having to go through the 
argument list to main().

(And my man page says this is a “standard C library” routine, so no need 
for POSIX even.)

For some reason this does not apply to argc and argv. I’ve often wished it 
did.
