Agree. ^^ Using ./contrib/download_prerequisites script is the simplest approach to cause them to be built automatically as part of GCC building process unless users want to build GCC with graphite loop optimizations. Are ppl/isl and cloog able to be built automatically like gmp/mpfr/mpc? I tried it before but never succeed, not sure whether it is ok on current trunk~ :p Best regards, jasonwucj
