--- Comment #6 from David Edelsohn <dje at gcc dot gnu.org> 2011-12-10 20:37:47 UTC --- This bug really should have been opened for the "classpath" Product in Bugzilla, not for "gcc". I do not think the bug can be transferred. The command definitely is wrong for AIX, but I don't think the option ever will be used when building classpath.
