You're right. Thanks for the heads up and sorry for the breakage!
I should have tested it with more compilers before committing it
(gcc doesn't issue a warning for it and neither does EDG eccp --
I opened http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29185).

Fixed thus: http://svn.apache.org/viewvc?view=rev&rev=449092

The warning is justified, even though the construct is actually
safe (although only because the value of second->off happens to
be the same as second).
