The work has now changed to GCC 4.8.2. It is being prepped
for import. The compiler work is basically done. At this point,
it is mostly making sure that NetBSD builds and runs with it.
Since I'm not doing the work, I don't have a timeline, but it
shouldn't be too much longer (FSVO much longer). This means that
sometime in the not too distant future anybody running -current,
or anybody that runs NetBSD 7.0 when it is released will be using
GCC 4.8.2 or later.
