I have been looking over an ANSI C book from the Waite Group (I forget the
name, it's very small and is a kind-of refrence).  Anyway it says that
volatile registers are NOT restored after a longjmp(), nor are register
variables, but auto variables are.  GCC documation seems to say that only
volatile variables are restored.  Do I understand the GCC docs correctly?
Is the Waite Group book wrong, or is GCC, or what?
