 DESCRIPTION
-        Return TRUE if the core file attached to @var{core_bfd}
-        was generated by a run of the executable file attached
-        to @var{exec_bfd}.  The match is based on executable
-        basenames only.
-
-        Note: When not able to determine the core file failing
-        command or the executable name, we still return TRUE even
-        though we're not sure that core file and executable match.
-        This is to avoid generating a false warning in situations
-        where we really don't know whether they match or not.
