This information is available via the DIGRAPH flag on tokens returned
by cpp_get_token, but I do not know if it is preserved all the way
through to this point in the C++ parser.
As with the case "foo <: : whatever", written that way in the source
code, it seems to me that this is not a mistake that anyone would
actually make, therefore I do not think it merits exception-to-
the-exception special treatment.
