Yes, of course. Free as in beer. Love it. However it would be nice, and I must find a way to find the right tone here such that I am not perceived as picking an argument for the sake of entertainment or some axe to grind, if the RTFM-averse crowd were told that "hey, no promise anything is up to date or even works" unless you build it yourself. > > There clearly seems to be a heavy leaning towards Linux distros here > > where Debian is directly mentioned and the assumption is made that > > pre-built ( by someone magic ) packages exist out in the world. > > Well, yes.

I am not up to speed on the GPL or BSD license language but I would think that Illumos or FreeBSD or OpenBSD would fall into the category of "free distros" however, let's not get obscure. Ever seen Illumos? I sure haven't an I should have. So yes, I think that being milk and cookie friendly to the Debian/Ubuntu folks makes sense. I get it.

The bits one gets from the cute download_prerequisites script are dusty at best. Thus : MPFR=mpfr-2.4.2 GMP=gmp-4.3.2 MPC=mpc-0.8.1 Well my most recent bootstraps of GCC 4.8.0 were done with : . . . < snippet from the libmpc testsuite report > GMP: include 5.1.1, lib 5.1.1 MPFR: include 3.1.2, lib 3.1.2 MPC: include 1.0.1, lib 1.0.1 C compiler: /usr/local/gcc4/bin/gcc GCC: yes GCC version: 4.7.2 PASS: tget_version =================== All 64 tests passed =================== The versions provided by the "download_prerequisites" are years behind the times and much has been done in those numerical software projects. So perhaps the script and the tarballs at ftp://gcc.gnu.org/pub/gcc/infrastructure/ could be brought into this decade? Couldn't hurt. Dennis
