I replaced a failing harddrive in one of my Debian machines today.
Instead of reinstalling Debian I decided to put Ubuntu on there. The
new Ubuntu comes with gcc 4.2.3:
> /usr/bin/gcc-4.2 -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v
--enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib
--without-included-gettext --enable-threads=posix --enable-nls
--with-gxx-include-dir=/usr/include/c++/4.2 --program-suffix=-4.2
--enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc
--enable-mpfr --enable-targets=all --enable-checking=release
--build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu
Thread model: posix
gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)
I can compile the latest git kernel on this new Ubuntu install with no
issues.
My problem is when I add distcc and gcc 4.1 back into the mix, a kernel
compile then fails with these errors:

Are my gcc's too different? I could swear I read somewhere any 4.x
gcc will work with any other 4.x version? Is that correct?
Is -fno-toplevel-reorder new in Linus' tree? I've been compiling git
kernels for some time now with gcc 4.1, but I do seem to recall some
gcc stack discussions lately on linux-kernel.
Thanks,
