Okay, sorry. It seemed like an issue that was already known, and simply 
not applied because of the very old glibc that I'm building, or for 
reason I don't understand.
Anyway, this URL
<http://cygwin.ru/ml/crossgcc/2009-02/msg00007.html>
seems to describe the change. See the last patch, which I will include 
here, for reference:

This patch is for a different (newer) version of glibc than I was using, 
but the same change still seems to apply.
I mentioned a failure of 1.7.0 to work for me as part of a prior post, 
and Yann suggested that I document it here on the list. As it is now of 
more or less academic interest to me, I am posting this for the benefit 
of others. More info upon request.
