Re: [9fans] 8c funny

yes, it's "only one prize per child".  if cc finds an error (or warning)
in an expression it generally bails on that item - avoiding the
"cascade of errors" from a simple typo.  sometimes it can be
annoying (fix "b" in this case and next compile it will complain
about "a") but usually it saves investigating non-errors.
