The gcc dependencies are reminding me of the pre-egcs days. I hope we don't
return there. :(

Anyway.. These are the sources I have linked into today's gcc-svn. This is what
I had been using over the holidays to test using Centos 6.x. But this isn't
working on a Fedora host.

Do you have to use any special configure option when using these sources inside
the gcc tree?
