This may be useful if you happen to #define some preprocessor-macros
that provide declarations.  It is useful to accept extra ';' so that
you may include semicolons in the macro and the user won't get an
error if he also adds one after the macro usage.

By the way, gcc won't accept this if you compile with flags:
-ansi -pedantic-errors
