Hi, I tried bootstrapping GCC 4.2.3 on x86-unknown-linux-gnu with the following configure:
/home/manuel/src/trunk/configure --prefix=/home/manuel/./131745/install --enable-languages=all --enable-decimal-float --with-mpfr=/home/ghazi/gcc-testing/lib/422-230/ But it failed. The last lines in the output are: Adding multilib support to Makefile in /home/manuel/src/trunk/libmudflap multidirs=32 with_multisubdir= Running configure in multilib subdirs 32 pwd: /home/manuel/131745M/build/x86_64-unknown-linux-gnu/libmudflap Running configure in multilib subdir 32 pwd: /home/manuel/131745M/build/x86_64-unknown-linux-gnu configure: creating cache ./config.cache checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes checking for --enable-version-specific-runtime-libs... no checking whether to enable maintainer-specific portions of Makefiles... no checking for x86_64-unknown-linux-gnu-gcc... /home/manuel/131745M/build/./gcc/xgcc -B/home/manuel/131745M/build/./gcc/ -B/home/manuel/./131745M/install/x86_64-unknown-l\ inux-gnu/bin/ -B/home/manuel/./131745M/install/x86_64-unknown-linux-gnu/lib/ -isystem /home/manuel/./131745M/install/x86_64-unknown-linux-gnu/include -isystem /home/man\ uel/./131745M/install/x86_64-unknown-linux-gnu/sys-include -m32 checking for C compiler default output file name... a.out checking whether the C compiler works... configure: error: cannot run C compiled programs.

If you meant to cross compile, use `--host'. See `config.log' for more details. GCC 4.3 bootstraps just fine with the same configuration. I am trying "--disable-multilibs" right now. Any other ideas? Cheers, Manuel.
