You are correct! I just checked with K&R and already back then they had it
"right". Thanks Bill, I learned something new today!

So, then gotos are stack-safe as they should be, and thus can't cause any
memory fragmentation (MCs argument). So, use them when applicable.

There is however a dangerous function in the C-library and for which MCs
comments still apply - the infamous long-jump. Now that function makes sense!
Long-jump is an accident waiting to happend.
