My sole point is that it needs to be specified---just saying "opaque"
derived type is insufficient in Fortran (I suspect also in C but I do
not know that language well-enough).

type", but do not have my C book at home today to check. It smells like
void* but it is different in some subtle ways, which I likely do not
