/* The constraints on storage class specifiers and function specifiers
   must be met for empty declarations where they are useless.  Thus
   there may be only one storage class specifier (C90 6.5.1, C99
   6.7.1#2) and "inline" must not be used because the declaration is
   not that of an identifier for a function (C99 6.7.4#1), and
   "register" and "auto" must not be used at file scope (C90 6.7, C99
   6.9#2).  */
