Ah, I see. It's warning you which variables have been given register
storage allocation by the compiler, and which therefore won't be unwound
properly when longjmp() takes you back up the stack to the setjmp() spot.
As long as none of those are referenced in the `if (setjmp(...)) { ... }'
blocks (which appears to be true), everything should be OK.
