Grievously, I don't think that this was ever resolved. There was
quite a discussion on the firstname.lastname@example.org mailing list in October of
last year, but it just seemed to run out of steam, and trail off,
without resolution. Could be wrong, and delt with otherwise, but I
don't think so. Definitely, according to Zack, Wind River has been
blest with the patch, but I can't find Zack Weinberg's patch in either
gcc 3.3 or the cvs repositories.
The original message containing Zack's patch can be found attached to
his e-mail here:

I'm attempting to include his patch in my efforts to compile gcc 3.3
from the gnu source.
