Hi, I was just trying to build the 4.3.1 release on RH5. During the configuration of libgcc, I get an error shown in the config.log file below. This looks like an error in the distributed config files. Or am I doing something wrong? I had no such problem IIRC building the 4.3.0 release. Thanks, Eric. /build/gcc-4.3.1/x86_64-unknown-linux-gnu/libgcc/config.log: ------------------------------------------------------------ This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake.
