I think that's a condition of life. The compilers are moving targets,
no matter that they allegedly implement standards. We endeavor to keep
HEAD able to compile warning-free on recent compilers, but I don't think
we can make such a promise for back branches. This thread offers a great
example of why not: the changes required would sometimes be too invasive
to be justifiable.
In the end, if you're building an old branch, you should be doing it with
old tools.
