--- Comment #15 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > You should add: > > --with-stage1-ldflags=-static-libstdc++ > --with-boot-ldflags=-static-libstdc++ > > to your configure line. With these lines added to my configure line I have been able to bootstrap revision r247792. However this addition was not necessary before and I don't think it is the end user responsibility to do the addition.
