stdatomic.h is part of gcc, and required by C11.  You must have a copy.

So you do have stdatomic.h.  Where is that file?  Must be a gcc config
error.

Can you post the entire build file?

Why do you want to use old gcc?

Can't say anything about that, no details....

Yeah, known issue.  Best to just wipe the source tree and start over.

Why?  gpsd already does that, several different ways.
