And they must not migrate to testing until the new glibc does.  Not only is
the new glibc the version they were tested with, but they will not run with
the older glibc.

I did check:

there:[~] grep-available -nsPackage -FDepends 'gcc ('

and it doesn't look like a problem to me. :-)

Let's wait until these bugs are actually filed before predicting doom, gloom
and the end of civilization as we know it, yes?  Keep in mind, gcc 3.2 also
_fixes_ a lot of long-standing bugs in 2.95, and there have been multiple
attempts to rebuild the archive with gcc 3.2 that have been largely
successful (a relatively small number of packages failed to build).
