According to the new K&R book return and exit should be equivalent in
ANSI C. However, I don't think this used to be the case before.

return is a C statement which causes main to return a value to its caller,
and this may prevent some necessary cleanup in older implementations.
exit is a library function which does the necessary cleanup and then
terminates the process.

Paul.
