I understand your explanation, but I don't think you're saying the
same thing as that comment. The comment is wrong, or perhaps it is
misleading/imprecise: one possible interpretation of the current
comment text is that it implies that there is no platform where
fortran INTEGER and C int are not the same representation -- and that
is wrong.

What I think you're saying is that that is not how the comment is
intended; that it is intended to say "we only support fortran integer
datatypes that have corresponding C integer datatypes." In which case
we should say *that*, not the misleading/imprecise comment that is
there now. :-)
