+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.
