--- Comment #20 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > Did you regen fixincl.x (with ./genfixes in the source tree)? I did a clean bootstrap, but I did know that I had to run ./genfixes. BTW you probably mean ./fixincludes/genfixes, isn't it? I am currently bootstrapping again with the patch in comment 15: machine busy for the next 2 hours.
