>What does the ANSI standard say about this?

The May 13, 1988 draft says that since "j" is of automatic storage
duration, isn't declared "volatile", and was changed between the calls
to "setjmp" and "longjmp", its value will be indeterminate after the
call to "longjmp".  Either behavior is conformant, as would be setting
"j" to 666....
