Do we want 1s for vaopt in the GNU rows, then? It seems to only be used
for controlling the pedwarn about needing at least one argument for the
variadic parameter.
+maybe_va_opt_error (cpp_reader *pfile, cpp_hashnode *node)
Do we also want to look at the va_opt option in this function, to
complain if pedantic and it isn't set?
