I located a couple of old machines to try, so I have two more successful build reports, and one failure (though don't worry about the failure yet).
First one (includes C, C++, ObjC, Fortran, and Java) i686-pc-linux-gnu on a RHEL 3 system. boot compiler: gcc 3.3.6 (FSF release) kernel: 2.4.21-32.EL (from Red Hat) glibc: 2.3.2-95.33 (from Red Hat) binutils: 2.17 (FSF release) GMP: 4.1.2-5 (from Red Hat) MPFR: 2.3.1 Results: http://gcc.gnu.org/ml/gcc-testresults/2008-09/msg00304.html The failures and noise are evidently due to the ancient glibc. Second one (includes C, C++, ObjC, and Fortran) hppa2.0w-hp-hpux11.00 This is an HP 9000/800/L1000-36 Bootstrapped with gcc 3.2.3. as is from binutils-2.18 (FSF), native linker gmp is 4.2.2 (FSF) mpfr is 2.3.1 (FSF) Results: http://gcc.gnu.org/ml/gcc-testresults/2008-09/msg00306.html No issues building GCC, I did have to turn off -Werror in a couple of places to get binutils 2.18 to build with gcc. I also found an ia64 box running Red Hat Advanced Workstation 2.1. Yes, I know, really old, but I can't change it. I tried a build using Bootstrap compiler is FSF gcc 3.2.3 kernel: kernel-2.4.18-e.12smp (from Red Hat) glibc: 2.2.4-29.2 (from Red Hat) binutils: 2.18 (FSF) gmp: 4.2.2 (FSF) mpfr: 2.3.1 (FSF) but the bootstrap died. gcc itself three-stage bootstrapped OK, then died during the multilib configuration for libgcc. It might just have been an issue with the shared library path, now that I look at it; I'll re-check.
