Using a goto to throw out of a call is a gcc extension, though.  (If
you don't mind depending on gcc, it _is_ cleaner; it completely avoids
the "need to mark it volatile" issue.  If the label is out of scope,
you can use a pointer to a nested function to reenter the label's scope
for purposes of the throw.)
