--- Comment #7 from David Edelsohn <dje at gcc dot gnu.org> --- Is protobufs even known to build on AIX? Whoever wrote the link command for AIX didn't know what they were doing and threw every option they could at the problem until it appeared to work. This is wrong. -bexpall -bsvr4 -brtl likely is very wrong. Until it's proven that this isn't cockpit error, this won't be analyzed or fixed.
