quick update as I know things are waiting on this..
gcc-4.6.1 bootstrap built ok (with java as usual, without cloog due to
then built libtool-2.4-6.fc15 which goes along with it
then built cloog
So far so good.
Now rebuilding the real, unmodified gcc-4.6.1 from f15 mainline.
Should be done in 2-3 days.
Then we will be good to continue with building the rest of the toolchain.
