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
