CC: Cobham Gaisler
The patches look good, but they touch grlib. I'm not sure if grlib in
rtems.git is "authoritative" or if Cobham Gaisler maintains an
upstream. So I'd like Daniel or someone to comment/approve before
these go in, and we should probably get to know that relationship and
document it in the sources.
