Oy -- I had forgotten about that. Sorry!
I think your only option at the moment is to separate the use of threads from your plpa_runtime.c file. I realize that that's a sucky answer, but that might be the final/only answer for PLPA. Sorry. :-(
hwloc is probably the best answer for the future -- as I mentioned, the embedding work is occurring right now and will be included in v1.0. It will not have this "override cpu_set_t" issue that PLPA does.
