Actually I went through and created the basis for that repo.  It
contains all branches and tags in the gcc svn repo and the final
pack comes to about 600M.  This has _everything_, not just trunk.

For the first time after doing such an import, I found it much better
to do git repack -a -f --depth=100 --window=100.  After that initial
repack a plain git-gc occasionally will be just fine.

If you want any more information about this, let me know.
