Alright, let's reopen for the sake of the discussion

I should have explained better.
I removed code that was touching
some_derived_type_symbol->f2k_derived->sym_root, which was never used.
The inheritance information is still present, through the type of the first
component of an extended type.

I don't think it is related to the patch I committed, because 4.9 also gives
the wrong result.
