Well, I don't know what changed to make this suddenly happen. FYI, here is
the configure line I have been using for quite some time:

../llvm-gcc-svn/configure \
    --prefix=/home/melis/llvm \
    --program-prefix=llvm- \
    --with-llvm=/home/melis/c/llvm-svn \
    --enable-languages=c,c++ \
    --target=i686-pc-linux-gnu \
    --with-tune=generic \
    --with-arch=pentium4
