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.
