    dev-libs/apr: fix miscompilation w/ Clang 16
    
    I've not sent these upstream unfortunately, for a few reasons:
    - a bunch of it is already there;
    - we have a huge backlog of patches we need to rebase/upstream;
    - upstream are way overdue a release in the 1.7.x branch (and it's a mess
    atm)
    
    Let's revisit this on the next release when it should be much easier.
