You're not being annoying.  In general, if you send me a message
explicitly (i.e., I'm in the To: or Cc: field), and you don't get a
reply, the right assumption is that either I've not replied yet, or that
I've somehow missed the message.  In either case, if you feel it's
urgent, please feel free to ping me again -- as you did here.

It doesn't look like that patch has been approved for mainline.  If it
is approved there, then it is OK for the 4.2 branch, after the 4.2.2
release.

Good catch.  Looking back at the build logs, I see:

/scratch/mitchell/gcc-releases/gcc-4.2.2-RC-20070927/gcc-4.2.2-RC-20070927/gcc/doc/include/gcc-common.texi:11:
@include `gcc-vers.texi': No such file or directory.

It looks like the problem here is that the release script builds the
documentation before building the compiler.  That used to work, but no
longer does, because the documentation now depends on a file that is
created by the build process.

So, the right fix is probably to (a) apply your patch or an equivalent,
and then (b) modify the release script so that instead of explicitly
building the installation docs before the compiler is built, it does
that afterwards -- or just relies on the compiler build to install the
documentation.

In either case, I don't think that this is a showstopper.  (AFAIK,
you're the first person to notice this, and you've indicated that it's
now a relatively long-standing bug.)

Thanks,
