Thanks, now it is obvious to me. So how should I configure my GCC-trunk build? It seems that --with-cpu is not enough: $ gcc -v Using built-in specs. Target: i686-pc-cygwin Configured with: ../configure --prefix=/opt/gcc-4.5-trunk -v --enable-bootstrap --enable-version-specific-runtime-libs --enable-static --enable-shared --enable- shared-libgcc --with-gnu-ld --with-gnu-as --enable-sjlj-exceptions --enable-lang uages=c,c++ --disable-symvers --enable-libjava --disable-nls --with-cpu=core2 -- enable-threads=posix Best regards Piotr Wyderski
