I've installed gcc 3.2.1 on Solaris 2.7, with binutils-2.13.1. I only built C, C++, and Fortran. The bootstrap compiler was gcc 2.95.2. Test results can be found in http://gcc.gnu.org/ml/gcc-testresults/2002-11/msg00766.html I'm seeing one libstdc++ failure: FAIL: 27_io/istream_extractor_arith.cc execution test I haven't investigated yet.
