Log Message:
-----------
this is a really tricky one. quell warnings about variables getting clobbered
after a longjmp or vfork by making them all static. we can do this here
because they're all just main() variables fortunately. bu's jump mechanism
uses setjump, so an implementation could clobber local non-static non-volatile
variables. this tricking making them static works or it would have also worked
to wrap the BU_SETJUMP/BU_UNSETJUMP calls into functions that are passed
parameters (i.e., no variables in that frame).
