--- Comment #11 from Marek Polacek <mpolacek at gcc dot gnu.org> --- I have tried bootstrap on AIX with .../configure --prefix=`pwd` --enable-checking=release --with-gmp=/opt/cfarm/gmp-latest/ --with-mpc=/opt/cfarm/mpc-latest/ --with-mpfr=/opt/cfarm/mpfr-latest/ && gmake -j16 2>&1 | tee LOG and both trunk and gcc-6-branch work.
