but there isn't a stdatomic.h until we support C1x right? didnt we bail 
on that last release until things were more settled?   I just presumed 
that those types are part of C1x and then fix it all up for C1x support 
in the next release since I don't think we are yet.

hmm, yeah I was thinking that file was compiled for the target, so it 
would work.  Guess its a host file so I do need to look at the nodes 
instead:-P
