This looks like some sort of transient failure, not related to the package:
Error Downloading Packages:
  gcc-4.4.0-12.x86_64: failure: Packages/gcc-4.4.0-12.x86_64.rpm from fedora: (256, 'No more mirrors to try.')

What should I do with this bug?  Mark it as CLOSED/TRYAGAIN later?

I'm rebuilding all the failed packages; transient build failures will get flagged as no longer failing, and I'll close those bugs later today.

This was a build system failure, not a package bug.  I apologize.

Matt, I just rebuilt this one -- we probably shouldn't close FTBFS bugreports until there is the build indeed present, otherwise we loose the ability to track them (IMO it's not important whether it is a package bug or a build system failure, we need to know and rebuild) :( I have actually some more thoughts about FTBFS bugs in relation with the mass rebuilds, I'll send them to you (and others) later.
