--- Comment #31 from David Edelsohn <dje at gcc dot gnu.org> --- I will test, but Flex and gengtype-lex.c does not appear to be the issue. If the change works, it will be coincidental. I have built the RC with gengtype-lex.c removed so that it is regenerated with the system Flex -- it still fails. I have build gcc-6-branch r235040 with gengtype-lex.c from the RC -- it works.
