Hi all,

the attached patch fixes PR 86116 by splitting up the function
'compare_type' into two variants: One that is used for checking
generic interfaces and operators (keeping the old name), and one that
is used for checking dummy functions and procedure pointer assignments
('compare_type_characteristics'). The latter calls the former, but
includes an additional check that must not be done when checking
generics.

Regtests cleanly on x86_64-linux-gnu. Ok for trunk?

Cheers,
Janus

    Call 'compare_type_characteristics' instead of 'compare_type'.
