        * dependency.h (gfc_dep_resovler): Add optional argument identical.
        * dependency.c (gfc_check_dependency): Do not alway return 1 if
        the symbol is the same. Pass on identical to gfc_dep_resolver.
        (gfc_check_element_vs_element): Whitespace fix.
        (gfc_dep_resolver): Adjust comment for function.  If identical is
        true, return 1 if any overlap has been found.
