Yes.

To do this (if I've understand you correctly) a global option is
needed, like defer_pragmas. I think this is not good, because in this
case we can't have some pragmas to be handled by cpplib on the fly,
and other pragmas to be tokenized. That is why the argument to
c_register_pragma is needed.
Maybe some kind of "default pragma handling mechanism" option?
