Thanks! That certainly clarifies things. Now I just need to get to coding. :)
We had a student working on adding restrict but he was working from home mostly. I need to get back with him now that he is back in school and start reviewing and submitting his patches.

i think POSIX dictates the defines and their values already. like here:

iiuc, when POSIX adds things, there's no guarantees that it adds everything at
once from a specific external spec, or at the same time. or when things get
removed. so different spec versions can yield a different feature set.
