Dear Andi (and/or other gcc programers): This is config.log file when I try to build 4.5.2 which failed at stage of make. plz help, thank a lot in advance. ----------------------------------------------------------------------------- root@eric-laptop:/home/eric/disk/gcc-4.5.2# cat /home/eric/disk/gcc-4.5.2/i686-pc-linux-gnu/libgcc/config.log This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake.
