I likely have something related to this in my stash of unmerged fixes, because I had something for #313 and #314 too.

Want to submit something for those three? Needed ASAP (blocking cert work).

Right now focusing on nasa/osal#285 stuff, but if it can wait until next week, then I can submit something.

Note that -Wcast-align was something we added recently, it never compiled cleanly on Vxworks/PPC. Whenever testing for vxworks I simply turned this warning off in the local build.
