Why are you filing it against gcc?  It is completely intentional.  Just
fix your package(s).

I didn't mean to denote that it was a (current) bug in gcc. I just meant
to let myself and others track the fact that the gcc 4.7.0 release (and
pre-releases) interact with this bug, and I meant to link to the
original gcc ticket: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24163

I guess ideally I would mark this ticket as applying to the list of
packages that you posted to the mailing list, but I don't know if that's
possible and if it is I'm not going to take the time to do it manually.

P.S. I guess I was thinking of "the package of gcc that is shipped in
Fedora" as being one of the subjects of this ticket, more than "gcc
itself". I figured it might help other people to understand that if they
are seeing these errors, it is the combination of gcc 4.7.0 pre-release
and their other packages that results in the errors. But again, I didn't
intend to say that the errors were caused by gcc having a bug. Also, of
course, Crypto++ and quite a few other packages are also the subjects of
this issue. The launchpad ticket --
https://bugs.launchpad.net/gcc/+bug/915018 -- has links to relevant
tickets in various issue trackers.

For my own future reference:

1. Is there a way to express in bugzilla.redhat.com that an issue
affects a package of software $X version $Y within Fedora release $Z?
Ideally I would have said "This is an issue you may have if you're using
the 4.7.0 pre-release distributed in Fedora Rawhide.". Is there a way to
express that in the bugzilla db?

2. Is there a way to denote "This is an issue that affects $X or that
the presence of $X can trigger, but is not a bug in $X?".

Thanks!
