--- Comment #32 from Jakub Jelinek <jakub at gcc dot gnu.org> --- But if gengtype-lex.c is not it, what it is then? I can't see how the generated man pages or *.html files or *.gmo or *.info files could affect it, so is the pathname? If you check out r235040 into the same directory as you tested the tarball in, does that work? Or is it the LAST_UPDATED file missing in the rc tarball?
