This comment fix can go in straight away as obvious.

Fixes for bugs that were user-visible in past releases should have an 
associated bug in Bugzilla with [BZ #N] in the ChangeLog entry and the bug 
number listed in NEWS as fixed (if the bug was fully fixed), and testcases 
for the testsuite may be a good idea as well (though we're less strict 
about that for system-specific bugs).  I know of at least bugs 5268 and 
14551 as known IBM long double bugs in glibc, although the former doesn't 
give a self-contained testcase so it's not clear what the bug is supposed 
to be there.  I don't know if those bugs correspond to some of what you're 
fixing or what other bugs might need to be filed to cover the fixes.
