--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
> From parser.h:

  } GTY((desc ("(%1.type == CPP_TEMPLATE_ID)"
               "|| (%1.type == CPP_NESTED_NAME_SPECIFIER)"
               "|| (%1.type == CPP_DECLTYPE)"))) u;

> If there's a space after the || operator, there should be one before the operator, too.

This one does not matter that much.  Because it is C code in the end.
